afl(data, frame.lab = NULL)

Value

A data.frame, with a frame.lab attribute added to the attributes meta-data

Arguments

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.
