Thanks for your reply Pascal
Thanks for your reply Pascal.
I am presently using it with sweep. But here in the question I just gave
one simple example. In reality I need several functions to run. Thus I
was wondering, if without sweep, I can use loop. Also want to learn how to
do this using loop.
Any help will be really grea
Hello,
If you *really* need a loop:
Data <- array(NA, dim(mdat))
for(i in 1:ncol(mdat)){
Data[,i] <- mdat[,i]*100/x[i]
}
But I would consider first the thread cited by Berend.
Regards,
Pascal

Hi,
?sweep
mdat <-
matrix(c(1,11,2,10,5,2,12,3,9,6,3,13,4,8,7,4,10,5,9,8,5,10,6,10,4),5,5)
x <- c(14,15,10,11,18)
sweep(mdat*100, 2, x, FUN='/')
[,1] [,2] [,3] [,4] [,5]
[1,] 7.142857 13.3 30 36.36364 27.8
[2,] 78.571429 80.0 130 90.90909 55.6
