dimnames(x) dimnames(x) <- nlist
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.
rownames, colnames;
array, matrix, data.frame.## simple versions of rownames and colnames ## could be defined as follows rownames0 <- function(x) dimnames(x)[[1]] colnames0 <- function(x) dimnames(x)[[2]]
