Hello R Experts,
  I need a bit of help in using loop.
I have a matrix onto which I need to use several functions.

In a simplified form suppose my matrix is
> mdat
     [,1] [,2] [,3] [,4] [,5]
[1,]    1    2    3    4    5
[2,]   11   12   13   10   10
[3,]    2    3    4    5    6
[4,]   10    9    8    9   10
[5,]    5    6    7    8    4

And I have one vector
> x
[1] 14 15 10 11 18

Now suppose in simple form I want to create a matrix in which each col
value will be divided with consecutive no from vector x. For example

column 1 of new vector will be C1=mdat[,1]*100/x[1]

> C1
[1]  7.142857 78.571429 14.285714 71.428571 35.714286

Now how can I use the loop to have the complete vector at a time?
I tried something like this, but in vain.
for(i in 1:5) {
Data=(mdat[,i]*100/x[i], add=T)
}

Any help will be really great.
Thanks,
Mitra
