checkDataset {PhenStat} | R Documentation

## Method "checkDataset"

### Description

Checks dataset for the minimum required info:

1. Column names should present

2. Genotype column should present

3. Sex column should present

4. Two data points for each Genotype/Sex combination

5. Number of Genotype levels should be 2

6. Number of Sex levels should be 1 or 2

7. Sex levels have to be "Female" and/or "Male"

8. Records with reference genotype should be in the dataset

9. Records with test genotype should be in the dataset

Perform the following additional checks:

- presence of Weight column,

- presence of Batch column (Assay.Date).

Warning given in case of missed data indicating that you can only fit a glm or to use MM equation "withoutWeight".

Function `checkDataset` is called from `PhenList` function.

### Usage

        checkDataset(dataset,
    				testGenotype,
    				refGenotype="+/+",
    				outputMessages=TRUE,
    				dataset.clean=TRUE)

### Arguments

`dataset` | data frame created from file or from another source; mandatory argument
`testGenotype` | defines the test genotype to be compared to the reference genotype; mandatory argument
`refGenotype` | defines the reference genotype; assigned default value is "+/+"
`outputMessages` | flag: "FALSE" value to suppress output messages; "TRUE" value to show output messages; assigned default value is TRUE
`dataset.clean` | flag: "FALSE" value for no modification of the dataset; "TRUE" value to clean dataset if needed; assigned default value is TRUE

### Value

Returns an instance of the `PhenList` class.
