get_label: Retrieve variable label(s) of labelled data

Description

This function retrieves the value labels of labelled data, which was created with the labelled or haven package, or imported from SPSS, SAS or STATA files (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_label(x, def.value = NULL)

Arguments

data.frame with variables that have label attributes (e.g. from an imported SPSS, SAS or STATA data set, via read_spss, read_sas or

def.value

Optional, a character string which will be returned as label if x has no label attribute. By default, NULL is returned.

Value

A named char vector with all variable labels from the data frame or list; or a simple char vector (of length 1) with the variable label, if x is a variable. If x is a single vector and has no label attribute, the value of def.value will be returned (which is by default NULL).

Details

See 'Details' in get_labels.

Examples

Run this code

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

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

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

data(efc)

# get variable lable
get_label(efc$e42dep)

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

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

# get labels from multiple variables
get_label(list(efc$e42dep,
               efc$e16sex,
               efc$e15relat))
