Create scale information.

Create information on scale or imputation aggregation. Scales, 'fake scales', and imputed variables are listed.

Usage

createScaleInfo(inputForDescriptives)

Arguments

inputForDescriptives

inputForDescriptives object as created by the createInputForDescriptives function

Value

Returns a data.frame or list of data.frames with the following information:

• varName The name of the variable as it occurs in the data

• Anzahl_valider_Werte For a scale, how many values have to be not NA on items for a non NA value on the scale?

• Items_der_Skala Which items or imputations belong to the scale? This column is used to display the item names in the codebook.

• Imputationen Which imputations belong to the pooled variable? This column is used to display the number of imputations in the codebook.

Details

Currently, displaying the items of a imputed scale is not supported by the codebook() function. Even though the items of an imputed scale can be defined in the scaleInfo, this information is simply ignored during the creation of the codebook.

Examples

# import spss exemplary data
file <- system.file("extdata", "example1_clean.sav", package = "eatCodebook")
dat   <- eatGADS::import_spss(file)
inputForDescriptives <- createInputForDescriptives(dat, impExpr = "plausible value")

scaleInfo <- createScaleInfo(inputForDescriptives)
