Check a GADSdat for labeled fractional values.

Source: R/checkLabeledFractionals.R
checkLabeledFractionals.Rd

Check a GADSdat object for any occurrences of fractional values in its metadata, including both "truly" labeled values and values tagged as missings.

Usage

checkLabeledFractionals(GADSdat)

Arguments

GADSdat

A GADSdat object.

Value

Returns a data.frame, listing the affected varNames, the labeled fractional values, their respective missings tags, and whether they actually occur in the data (empty).

Details

This function is mainly useful to ensure a data set can be saved as a .dta file. Unlike, for example, SPSS, Stata only allows for integer values (and so-called extended missing values) to be labeled (Stata manual: 12.6.3). Trying to export (meta) data with labeled fractional values would therefore cause problems and run into an error from haven's write_dta function.

Examples

# Introduce a fractional value into meta data
pisa2 <- recodeGADS(GADSdat = pisa,
                    varName = "schtype",
                    oldValues = 2,
                    newValues = .5)
checkLabeledFractionals(pisa2)
#>   varName value missings empty
#> 1 schtype   0.5    valid FALSE
