Base function for flipping matrices

Sat, Dec 31, 2011 7:08 AM

Hi all,

Are there base functions that do the equivalent of this?

fliptb <- function(x) x[nrow(x):1, ]
fliplr <- function(x) x[, nrow(x):1]

Obviously not hard to implement (although it needs some more checks),
just wondering if it had already been implemented.
