Dimnames of an Object

Usage

dimnames(x)
dimnames(x) <- nlist

Description

Retrieve or set the dimnames of an object.

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.

See Also

rownames, colnames; array, matrix, data.frame.

Examples

## simple versions of rownames and colnames
## could be defined as follows
rownames0 <- function(x) dimnames(x)[[1]]
colnames0 <- function(x) dimnames(x)[[2]]
