dbImport {plethy} | R Documentation

## Import data into a BuxcoDB database

### Description

The main purpose of this function is to add data originally retrieved from the `retrieveData` method into a new or existing `BuxcoDB` database. This will most frequently be useful in the context of a merging procedure, however it also can facilitate data sharing and/or communication between seperate DBMS systems.

### Usage

    dbImport(bux.db = NULL, bux.dta, db.name = "merge_test_1.db", debug = FALSE)

### Arguments

`bux.db` | Either NULL or a `BuxcoDB` object
`bux.dta` | A `data.frame` consistent with the database structure of the `BuxcoDB` database, most easily created from a call to `retrieveData`.
`db.name` | Path to the new SQLite database to create.
`debug` | Logical value indicating whether the function should be more verbose.

### Details

If only `bux.dta` is supplied and not bux.db, then a new database will be created and populated at `db.name` from its contents. If both `db.name` and `bux.dta` are supplied then the `data.frame` will be loaded into the existing database.

### Value

A `BuxcoDB` object pointing to the newly created database.

### Examples

    bux.db <- makeBuxcoDB(sample.db.path())

    samp.1 <- retrieveData(bux.db, samples="8034x13140_5")

    test.db <- "test_db.db"

    if (file.exists(test.db))
    {
    	file.remove(test.db)
    }

    #create a new database from the output
    db.1 <- dbImport(bux.db=NULL, bux.dta=samp.1, db.name=test.db)

    samples(db.1)

    test.db.2 <- "test_db_2.db"

    if (file.exists(test.db.2))
    {
    	file.remove(test.db.2)
    }

    samp.2 <- retrieveData(bux.db, samples="8034x13140_11")

    db.2 <- dbImport(bux.db=db.1, bux.dta=samp.2, db.name=test.db.2)

    samples(db.2)

    file.remove(test.db.2)
    file.remove(test.db)
