drop_frame_lab {labelr}

Remove Frame Label Attribute from a Data Frame

Description

Remove the frame label attribute (see add_frame_lab) from a data.frame, if one is present.

Usage

drop_frame_lab(data)

dfl(data)

Arguments

data

the data.frame with a frame label that you wish to drop (and which was added using add_frame_lab).

Details

See add_frame_lab for more on this labeling construct.

Note: dfl is a compact alias for drop_frame_lab: they do the same thing, and the former is easier to type.

Value

a data.frame (with any previously applied frame.lab attribute removed).

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

get_frame_lab(mt2) # return frame.lab alongside data.frame name as a data.frame
drop_frame_lab(mt2) # remove this frame.lab
get_frame_lab(mt2) # the data.frame name now doubles as its frame label
is.null(attributes(data)[["frame.lab"]]) # the attribute is NULL
