Description

Assign variable labels to a data.frame from a lookup table.

Usage

set_labels(data, names_labels)

Arguments

data	data frame to be labelled
names_labels	data frame with column 1 containing variable names from data and column 2 containing variable labels. Other columns will be ignored.

Details

Useful if variable labels have been imported from a data dictionary. The first column in names_labels must contain the variable name and the second column the variable label. The column names are not used.

If no label is provided then the existing label will not be changed. To remove a label set the label to NA.
