[R] creating files using for loop

[Brian Quinif]

I would like to use a for loop to run estimations on 12 different
subsets of a dataset.

I have the basics of my script figured out, but I am having problems
getting the loop to name some files as I would like.   Here is a
sketch of my code:

sub.dataset <- c(101, 201)
#Assume I only have two subsets which I call 101 and 201

for (i in 1:length(sub.dataset)) {
#Estimation commands here...unimportant for this question
#Estimates <- matrix of estimation resultsI will write out to LaTeX
latex(Estimates, file=sub.dataset[i].tex)
}

So, the latex command is what's problematic here.  How can I get my
for loop to put file='101.tex' and file='201.tex' (or many similar
things) where I want it to.  I could just as easily want to put
something like 101$variable1 or 201$variable1.

Sorry for such a basic question regarding for loops, but thanks for the help.
