get_frame_lab {labelr} | R Documentation |
Return a Data Frame's Frame Label
Description
For a frame-labeled data.frame, get_frame_lab
returns a derivative
1x2 data.frame that lists the data.frame name and its frame.lab attribute.
Note: gfl
is a compact alias for get_frame_lab
: they do the same thing,
and the former is easier to type.
Usage
get_frame_lab(data)
gfl(data)
Arguments
data |
a data.frame. |
Details
get_frame_lab
returns the overall descriptive "frame label" that is assigned
to a data.frame using add_frame_lab.
Value
A 1x2 data.frame, consisting of "data.frame" and "frame.lab" values for the supplied data.frame. If the supplied data.frame does not have a frame label, its name also will be used as its frame label (i.e., both entries of the returned 1x2 data.frame will be the data.frame name).
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
Velleman (1981), Building multiple regression models
interactively. Biometrics, 37, 391–411.")
attr(mt2, "frame.lab") # check for attribute
# return frame.lab alongside data.frame name as a data.frame
get_frame_lab(mt2)
