dimnames {base} | R Documentation |
Dimnames of an Object
Description
Retrieve or set the dimnames of an object.
Usage
dimnames(x)
dimnames(x) <- nlist
Details
The functions dimnames
and dimnames<-
are generic.
For an array
(and hence in particular, for a
matrix
), they retrieve or
set the dimnames
attribute (see attributes) of the object.
Both have methods for data frames. The dimnames of a data frame are
its row.names
attribute and its names
.

colnames0 <- function(x) dimnames(x)[[2]]
