## About this vignette

This vignette follows a single instrument through the complete surveyframe
workflow: design the questionnaire, export it as a hosted survey with a Google
Sheets backend, collect responses, clean and score them, run the analysis plan,
and render a results report. The results section uses 60 simulated responses so
the vignette builds offline. Replacing the simulated data with a call to
`read_sheet_responses()` connects the same workflow to live responses that grow
with each submission.

The questionnaire and concept are adopted from:

> Sharafuddin, M. A., Madhavan, M., & Wangtueai, S. (2024). Assessing the
> Effectiveness of Digital Marketing in Enhancing Tourist Experiences and
> Satisfaction: A Study of Thailand's Tourism Services. *Administrative
> Sciences*, *14*(11), 273. https://doi.org/10.3390/admsci14110273

The instrument covers five research areas applicable to any tourism services
context: digital marketing effectiveness (relevance, accessibility, ease of use,
and perceived value), destination service quality (accommodation and local
transport), destination sustainability quality, tourist satisfaction, and
behavioural intention. The item wording is reproduced from the original
questionnaire. Researchers studying other destinations can adapt the scales
and analysis plan to their own context.

## The questionnaire

### Shared Likert scale

All rated items use a five-point agreement scale.

```{r choices}
likert5 <- sf_choices(
  "likert5",
  values = 1:5,
  labels = c("Strongly disagree", "Disagree",
             "Neither agree nor disagree", "Agree", "Strongly agree")
)
```

### Helper functions

`stem_items()` builds items that share a common sentence stem. Each item is the
stem followed by a unique completion. `solo_items()` builds standalone items.
Neither function is exported; both use only `sf_item()`.

```{r helpers}
stem_items <- function(ids, stem, completions, scale_id) {
  Map(
    function(id, comp)
      sf_item(id, paste(stem, comp),
              type = "likert", required = TRUE,
              choice_set = "likert5", scale_id = scale_id),
    ids, completions
  )
}

solo_items <- function(ids, labels, scale_id) {
  Map(
    function(id, lab)
      sf_item(id, lab,
              type = "likert", required = TRUE,
              choice_set = "likert5", scale_id = scale_id),

### Assemble the instrument

```{r assemble}
choice_sets <- list(
  likert5, gender_cs, age_cs, visitor_cs, freq_cs, nationality_cs,
  education_cs, profession_cs, companion_cs, group_cs
)

rated_items <- c(dmre_items, dmau_items, dmeu_items, dmpv_items,
                 dsqa_items, dsqt_items, dsuq_items, ts_items, bi_items)

study <- sf_instrument(
  title       = "Digital Marketing Effectiveness of Tourism Services",
  version     = "1.0.0",
  description = paste(
    "Questionnaire covering digital marketing effectiveness,",
    "destination service quality, sustainability quality,",
    "tourist satisfaction, and behavioural intention.",
    "Adopted from Sharafuddin, Madhavan & Wangtueai (2024),",

## Validate and serialise

`validate_sframe()` checks every item ID, choice set reference, and scale
membership before any data is collected. `write_sframe()` saves the validated
instrument with a SHA-256 hash so any post-collection edits are detectable.

```{r validate}
v <- validate_sframe(study, strict = FALSE)
v$valid
length(v$problems)
```

```{r write}
# Save the instrument. Keep this file alongside your analysis script.
sframe_path <- write_sframe(study, file.path(tempdir(), "tourism_services_v1.sframe"),
                             overwrite = TRUE)

# Reload the instrument from disk at any time with:
study2 <- read_sframe(sframe_path)
identical(study$meta$title, study2$meta$title)
```

---

## Set up data collection

### Store the Google Sheets endpoint in the instrument

When an endpoint URL is set on the instrument, `export_static_survey()` reads it
automatically. Set the URL once, export as many times as needed without
repeating the argument.

```{r endpoint, eval = FALSE}
# Replace with your deployed Apps Script URL after the setup steps below.
study$render$google_sheets_endpoint <-
  "https://script.google.com/macros/s/YOUR_SCRIPT_ID/exec"
```

### Export the static HTML survey

`export_static_survey()` produces a single self-contained HTML file. Respondents
open it in any browser, fill it in, and their submission is downloaded as a CSV
and, if an endpoint is configured, posted to the Google Sheet at the same time.
The file can be hosted on GitHub Pages, shared by email, or opened directly from
disk.

```{r static-export}
html_path <- export_static_survey(
  study,
  output_path = file.path(tempdir(), "tourism_services_survey.html"),
  open        = FALSE
)
file.exists(html_path)
```

### Generate the Google Sheets collector script

`export_google_sheet()` writes a Google Apps Script file. Deploy it in a Google
Sheet and it creates a response tab with the correct column headers, including
one column per matrix sub-item.

```{r gs-export}
script_path <- export_google_sheet(
  study,
  sheet_url  = "https://docs.google.com/spreadsheets/d/YOUR_SHEET_ID",
  output_dir = tempdir()
)
file.exists(script_path)
```

**To deploy the script:**

1. Open or create a Google Sheet.
2. Click Extensions, then Apps Script.
3. Paste the contents of the generated `.gs` file, replacing any existing code.
4. Click Deploy, then New deployment. Set type to Web app.
5. Set "Who has access" to Anyone.
6. Copy the Web App URL.
7. Paste the URL into `study$render$google_sheets_endpoint` above and
   re-export the survey.

### Pull live responses

Once the survey is live, read the growing response set with one call. Re-run
this line and everything below it to refresh all results.

```{r live-read, eval = FALSE}
responses <- read_sheet_responses(
  sheet_id   = "YOUR_SHEET_ID",
  instrument = study
)
```

---

## Simulated responses for offline demonstration

The code block below generates 60 plausible responses so the remainder of this
vignette runs without a network connection. Replace `responses` with the output
of `read_sheet_responses()` and re-run from the quality section onward to use
real data.

```{r simulate}
set.seed(2024)
n <- 60

# Each construct is driven by a latent score plus item-level noise.
# Correlations between constructs are introduced by sharing variance.
lat <- function(mu, sigma) pmax(1, pmin(5, round(rnorm(n, mu, sigma))))
add_noise <- function(x, sigma = 0.45) {
  pmax(1L, pmin(5L, as.integer(round(x + rnorm(n, 0, sigma)))))
}

# Higher service quality and sustainability lift satisfaction.
lat_dsqa <- lat(3.7, 0.6)
lat_dsqt <- lat(3.6, 0.6)
lat_dsuq <- lat(3.5, 0.6)
lat_ts   <- pmax(1, pmin(5, round(
  0.4 * lat_dsqa + 0.3 * lat_dsqt + 0.2 * lat_dsuq + rnorm(n, 0.6, 0.3)
)))
lat_bi   <- pmax(1, pmin(5, round(0.7 * lat_ts + rnorm(n, 0.5, 0.4))))

# Digital marketing constructs are loosely correlated with each other.
lat_dmre <- lat(3.8, 0.6)
lat_dmau <- pmax(1, pmin(5, round(0.5 * lat_dmre + rnorm(n, 1.9, 0.4))))
lat_dmeu <- pmax(1, pmin(5, round(0.4 * lat_dmre + rnorm(n, 2.2, 0.4))))
lat_dmpv <- pmax(1, pmin(5, round(0.3 * lat_dmre + rnorm(n, 2.5, 0.4))))

# Repeat visitors score slightly higher on satisfaction and intention.
visitor_type <- sample(c("first_time", "repeat"), n,
                       replace = TRUE, prob = c(0.45, 0.55))
lat_ts[visitor_type == "repeat"] <- pmin(5L, lat_ts[visitor_type == "repeat"] + 1L)
lat_bi[visitor_type == "repeat"] <- pmin(5L, lat_bi[visitor_type == "repeat"] + 1L)

# Build item columns from latent scores.

# Align the data frame to the instrument.
responses <- read_responses(sim_df, study,
                             respondent_id = "respondent_id",
                             submitted_at  = "submitted_at",
                             meta_cols     = "started_at",
                             strict        = FALSE)

cat("Respondents:", nrow(responses), "\n")
cat("Columns:    ", ncol(responses), "\n")
```

---

## Quality checks

```{r quality}
qr <- quality_report(responses, study, respondent_id = "respondent_id")
cat("Respondents:", qr$summary$n_respondents, "\n")
cat("Items:      ", qr$summary$n_items,       "\n")
cat("Flagged:    ", qr$summary$n_flagged,      "\n")
```

The flagged count reflects straight-lining detection on simulated data, where
random responses often repeat values. With real survey responses the flagging
rate is typically much lower. The flag marks respondents for researcher review,
not automatic exclusion.

```{r missing}
mr <- missing_data_report(responses, study)
# mr is a list; $item_missing, $respondent_missing, $mcar, and $apa are the
# main slots. Check names(mr) to see all available components.
names(mr)
items_miss <- mr$item_missing
items_miss[items_miss$missing_pct > 0, c("variable", "missing_n", "missing_pct")]
# $apa provides a plain-language summary suitable for a methods section.
cat(mr$apa, "\n")
```

---

## Score and describe

`score_scales()` appends one column per scale to the data frame, using the
scoring rules stored in the instrument.

```{r score}
scored <- score_scales(responses, study)

scale_cols <- c("DMRE", "DMAU", "DMEU", "DMPV",
                "DSQA", "DSQT", "DSUQ", "TS", "BI")
round(colMeans(scored[, scale_cols], na.rm = TRUE), 2)
```

---

## Reliability

```{r reliability}
if (requireNamespace("psych", quietly = TRUE)) {
  rr <- reliability_report(scored, study, omega = FALSE)
  print(rr)
}
```

A Cronbach's alpha of 0.70 or above is conventionally accepted as adequate
internal consistency (Nunnally, 1978). For scales with three or more items,
McDonald's omega is a more accurate estimate; pass `omega = TRUE` to include
it. See `?reliability_report` for details.

---

## Analysis plan

The plan binds each research question to a statistical technique and the
variable roles it needs. `run_analysis_plan()` executes every block and returns
one result per question.

```{r plan}
study$analysis_plan <- list(
  list(
    id               = "RQ1",
    research_question = "Are digital marketing perceptions associated with tourist satisfaction?",
    family           = "association",
    method           = "correlation_pearson",
    roles            = list(x = "DMRE", y = "TS"),
    options          = list(alpha = 0.05)
  ),
  list(
    id               = "RQ2",
    research_question = "Is service quality associated with tourist satisfaction?",
    family           = "association",
    method           = "correlation_pearson",
    roles            = list(x = "DSQT", y = "TS"),
    options          = list(alpha = 0.05)
  ),
  list(

## Run the analysis plan

```{r run-plan}
results <- run_analysis_plan(scored, study)
```

Each result carries an APA-formatted statistic, an effect size, a writing
prompt, and the methodological reference that supports the chosen test.

```{r show-results}
for (r in results) {
  cat(sprintf("[%s] %s\n  APA:    %s\n  Effect: %s\n  Prompt: %s\n\n",
              r$id,
              r$research_question,
              r$apa,
              r$effect_label,
              r$prompt))
}
```

The `prompt` field is a sentence template for the methods or results section.
The researcher fills in the substantive interpretation; the package supplies
the statistic and the label. This separation is intentional: statistical
significance and practical significance are distinct judgements.

## Results report

`render_results()` writes one section per research question. `render_report()`
adds a codebook, quality summary, and descriptives alongside the analysis
results.

```{r render-results}
results_path <- render_results(
  results,
  study,
  output_file = file.path(tempdir(), "tourism_results.html")
)
cat("Results report written:", results_path, "\n")
cat("Size:", round(file.size(results_path) / 1024, 1), "KB\n")
```

The results report contains one section per research question, with the APA
statistic, effect size, writing prompt, and the reference for the chosen method.

```{r render-report}
render_report(
  study,
  data             = scored,
  output_file      = file.path(tempdir(), "tourism_report.html"),
  include_codebook = TRUE,
  include_quality  = TRUE,
  include_missing  = TRUE,
  include_descriptives = TRUE,
  include_reliability  = TRUE,
  include_analysis = TRUE,
  include_models   = FALSE
)
```

## The live workflow

The section below shows the full sequence from a live Google Sheet. Every step
from `read_sheet_responses()` onward is identical to the simulated workflow.
Re-run this block each time you want updated results.

```{r live-workflow, eval = FALSE}
# 1. Pull the latest responses from the Google Sheet.
responses <- read_sheet_responses(
  sheet_id   = "YOUR_SHEET_ID",
  instrument = study
)

# 2. Run quality checks on the new data.
quality_report(responses, study, respondent_id = "respondent_id")

# 3. Score the scales.
scored <- score_scales(responses, study)

# 4. Run the pre-declared analysis plan.
results <- run_analysis_plan(scored, study)

# 5. Render the updated report.
render_report(
  study,
  data             = scored,
  output_file      = "tourism_report_latest.html",
  include_codebook = TRUE,
  include_quality  = TRUE,
  include_missing  = TRUE,
  include_descriptives = TRUE,
  include_reliability  = TRUE,
  include_analysis = TRUE,
  include_models   = FALSE
)
```

As more respondents complete the survey, re-running from the
`read_sheet_responses()` call above refreshes every result, table, and figure
in the report without changing any analysis code.

## Summary

The instrument built in this vignette can be loaded into SurveyBuilder for
visual editing or distributed directly as the exported HTML file. The Google
Sheets script connects online submissions to R through a single function call.
Because the questionnaire, the scales, and the analysis plan are stored together
in the sframe, the design and the analysis travel as one object.
