[R] using variable from for loop in naming new variables

[Greg Snow]

This is FAQ 7.21.

Note that the most important part of the FAQ is the last few lines where it essentially says "DON'T DO THIS".  If this is just a model for a bigger situation then definitely Don't Do This, as using assign and global variables will just create more and bigger future headaches.  Use another data structure like a list and all this becomes much easier.
