Description

This function retrieves the value labels of an imported SPSS, SAS or STATA data set (via read_spss, read_sas or read_stata) and

• ifxis a data frame or a list of variables, returns the all variable labels as names character vector of lengthncol(x).
• or, ifxis a vector, returns the variable label as string.

Usage

get_var_labels(x)

Arguments

a data.frame with variables that have attached variable labels (e.g. from an imported SPSS, SAS or STATA data set, via read_spss, read

Examples

# import SPSS data set
# mydat <- read_spss("my_spss_data.sav", enc="UTF-8")

# retrieve variable labels
# mydat.var <- get_var_labels(mydat)

# retrieve value labels
# mydat.val <- get_val_labels(mydat)

data(efc)

# get variable lable
get_var_labels(efc$e42dep)

# alternative way
get_var_labels(efc)["e42dep"]

# simple barplot
barplot(table(efc$e42dep))
# get value labels to annotate barplot
barplot(table(efc$e42dep),
        names.arg = get_val_labels(efc$e42dep),
        main = get_var_labels(efc$e42dep))

# get labels from multiple variables

                    efc$e16sex,
