randomize - R-help | R Mailing Lists

Dear helpeRs,

I am looking for an R equivalent of the S function "randomize" but 
cannot find it anywhere (?randomize, help.search("randomize")).  There 
are some references to "Randomize()" in the list archives, but it is not 
on my system (R 2.1.1 on Windows XP)... what package is it in?

Thanks!

Luis

Try help.search('random').  You can probably use sample (see ?sample) to do
what you  want.  Others may have a more direct equivalent.

In principle, you are looking for sample().

If you don't need other values for the "restrict" argument than the 
default, you can simply define:

randomize <- function(x)
   sample(seq(nrow(x)))
