I don't think I understand your question but John Fox has written a very
nice documentat about scoping and environments on his website.
It's probably easy to find the site by googling "John Fox" but, if you
can't find it, let me know.
As I said, I don't think that I understand your question but, if you
loaded a list variable using load("whatever.Rdata"), the variable will
just be suitting in your workspace. You don't need to attach anything
because load just loads the data right into the workspace.
So typing the variable name should show the data.

Subject: [R] how can I attach a variable stored in
Hi -
Any help would be greatly appreciated.
I'm loading a list variable that's stored in an .RData file and would
like attach it.
I've used attach( <file_name> ), but that only lets me see the variable
that's stored in the file.
As the variable name is of the form "comp.x.x", I've tried using attach(
ls( pat="comp" ) ), but get an error as ls() just gives back a string.
I've also played around with eval(), but don't really quite get what
that function does since it seems to get into the R internals which I
don't entirely understand and I haven't found any great unified
documentation on R's handling environment and scoping.
Thanks,
Peter Waltman
