Usage

setRowNames(x, rowNames)

Arguments

rowNames	New names for rows

Examples

setRowNames(matrix(1:4, nrow=2, ncol=2), c("a","b"))
setRowNames(matrix(1:4, nrow=2, ncol=2), NULL)
setRowNames(array(1:8, dim=c(2,2,2)), c("a","b"))
setRowNames(as.data.frame(matrix(1:4, nrow=2, ncol=2)), c("a","b"))
## Not run: setRowNames(as.data.frame(matrix(1:4, nrow=2, ncol=2)), NULL) # Is this a BUG?!
## Not run: setRowNames(1:2, c("a","b")) # Error 'dimnames' applied to non-array
