R help - Mar 2010 - Substitute of a For Loop

Hi,

I am trying to permute a vector for 1000 times for which I am using for
loop.Within the for loop, I am doing some matrix operations which is taking
a lot of time. I am looking for a way to permute the vector 1000 times and
do the operations of the matrix without using for loop. This a snippet of my
code:

    for (i in 2:1000){
        y.permute = permute(y.permute) ### permute the vector
        F.stats = calPseudoStat(y.permute,table.Gij) ## call the function
which does some matrix calculation and calculates a pseudo statistics
        F.stats.vec = append(F.stats.vec, F.stats) ## add the Pseudo
Statistics in a vector.
    }

Thanks.
