copy_labels: Copy value and variable labels to (subsetted) data frames

Description

Subsetting-functions usually drop value and variable labels from subsetted data frames (if the original data frame has value and variable label attributes). This function copies these value and variable labels back to subsetted data frames that have been subsetted, for instance, with subset.

Usage

copy_labels(df_new, df_origin = NULL)

Arguments

df_new

The new, subsetted data frame.

df_origin

The original data frame where the subset (df_new) stems from; use NULL, if value and variable labels from df_new should be removed.

Value

Returns df_new with either removed value and variable label attributes (if df_origin = NULL) or with copied value and variable label attributes (if df_origin was the original subsetted data frame).

Examples

data(efc)
efc.sub <- subset(efc, subset = e16sex == 1, select = c(4:8))
str(efc.sub)

efc.sub <- copy_labels(efc.sub, efc)
str(efc.sub)

efc.sub <- copy_labels(efc.sub)
str(efc.sub)
