R help - Jan 2010 - Choose variables according to index

Hi

There must have someone already posted this question but I still have not
figured how I could do this:
Say I have var.1 var.2 var.3 which are large matrices. I would like to do
the following loop:

for(i in 1:3){
  # Pick var.i and do something with it
}

How can I tell R to do this?

Thanks for any comments.

Put your var.n to list

lll<- list(var.1, var.2, var.3)

and use list indexing

temp.mat <- lll[[i]]

do stuff with temp.mat
