apply_labels: Set variable labels/value labels on variables in the data.frame

Description

apply_labels tries automatically detect what is variable label and what are value labels. See also var_lab and val_lab.

Usage

apply_labels(data, ...)

Value

data with applied labels

Arguments

data

data.frame/list

...

named arguments or lists. Name of argument is a variable name in the data. Argument values are variable or value labels. Unnamed characters of length 1 are considered as variable labels and named vectors are considered as value labels. List arguments should be named lists and contain value and variable labels.

Examples

data(mtcars)
mtcars = apply_labels(mtcars,
                      vs = "Engine",
                      vs = num_lab("
                             0 V-engine 
                             1 Straight engine
                             "),
                      am = "Transmission",
                      am = num_lab("
                             0 Automatic 
                             1 Manual
                             ")
)

# 'table' from base R
table(mtcars$vs, mtcars$am)

# more sophisticated crosstable
cross_cases(mtcars, vs, am)

# the same but with list argument
list_arg = list( vs = "Engine",
                 vs = num_lab("
                             0 V-engine 
                             1 Straight engine
                             "),
                 am = "Transmission",
                 am = num_lab("
                             0 Automatic 
                             1 Manual
                             ")
                 )
