Transform dummy variables to character variables.

Source: R/dummies2char.R
dummies2char.Rd

Convert a set of dummy variables into a set of character variables.

Usage

dummies2char(GADSdat, dummies, dummyValues, charNames, checkVarNames = TRUE)

Arguments

GADSdat

A GADSdat object.

dummies

A character vector with the names of the dummy variables.

dummyValues

A vector with the values which the dummy variables represent.

charNames

A character vector containing the new variable names.

checkVarNames

Logical. Should charNames be checked by checkVarNames?

Value

Returns a GADSdat.

Details

A set of dummy variables is transformed to an equal number of character variables. The character variables are aligned to the left and the remaining character variables are set to NA. For each new variable the missing codes of the respective dummy variable are reused.

Examples

## create an example GADSdat
dummy_df <- data.frame(d1 = c("eng", "no eng", "eng"),
                      d2 = c("french", "french", "no french"),
                      d3 = c("no ger", "ger", "no ger"),
                      stringsAsFactors = TRUE)
dummy_g <- import_DF(dummy_df)

## transform dummy variables
dummy_g2 <- dummies2char(dummy_g, dummies = c("d1", "d2", "d3"),
                        dummyValues = c("english", "french", "german"),
                        charNames = c("char1", "char2", "char3"))
