R help - Aug 2005 - randomize

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)))
