[R] For Loop

[Bert Gunter]

Bob:

Please, please spend some time with an R tutorial or two before you post
here. This list can help, but I think we assume that you have already made
an effort to learn basic R on your own. Your question is about as basic as
it gets, so it appears to me that you have not done this. There are many
many R tutorials out there. Some suggestions, by no means comprehensive,
can be found here:

Others will no doubt respond, but you can answer it yourself after only a
few minutes with most R tutorials.

Cheers,
Bert
