In labelr: Label Data Frames, Variables, and Values

Add a 500-or-fewer-characters high-level descriptive label for your data.frame as whole (e.g., nature, originator, population / sample, year created, general contents, article citation).

Usage

add_frame_lab(data, frame.lab = NULL)

afl(data, frame.lab = NULL)

Arguments

data	a data.frame.
frame.lab	quoted text of the descriptive data.frame label that you wish to add to the data.frame.

Details

add_frame_lab assigns an overall descriptive "frame label" for a data.frame, which can be retrieved using get_frame_lab.

Examples

# add frame.lab to mtcars and assign to new data.frame mt2
mt2 <- add_frame_lab(mtcars, frame.lab = "Data extracted from the 1974 Motor
                    Trend US magazine, comprising fuel consumption and 10
                    aspects of automobile design and performance for 32
                    automobiles (1973–74 models). Source: Henderson and
