Assigns a label to a vector or data frame, or returns value stored
in the object's label
attribute (or NA
if none exists).
label(x, all = FALSE, fallback = FALSE, simplify = FALSE)
label(x) <- value
llabel(x, all = TRUE, fallback = FALSE, simplify = FALSE)
A single character vector if all = FALSE
(default),
or a named list if all = TRUE
(named vector when using
simplify = TRUE
.
An R object to extract labels from.
Logical. When x is a data frame, setting this argument to
TRUE
will make the function return all variable labels. By
default, its value is FALSE
, so that if x is a data frame, it is
the data frame's label itself that will be returned.
a logical value indicating if labels (returned values)
should fallback to object name(s). Defaults to FALSE
.
When x is a data frame and all = TRUE
, coerce
results to a vector and remove NA
's. Default is FALSE
.
String to be used as label. To clear existing labels, use
NA
or NULL
.

The wrapper function llabel
was named that way to avoid conflicting
with base function labels
