Ivan,
Try this:
eval(parse(text=paste("save(file", i, ", file=\"file", i, ".RData\")", sep="")))

> Dear users,
My problem concerns save() within a for loop.
Here is my
> code:
for (i in 1:4) {
temp <- data.frame(a=(i+1):(i+10),
> b=LETTERS[(i+1):(i+10)])
filename <- paste("file", i, sep="")
> assign(filename, temp)
save(filename, file=paste(filename, ".rda",
> sep=""))
}
As you can see, save() doesn't work as I would like: (1)
> the object saved is called "filename" (instead of "file1", "file2", etc), and
> (2) it of course contains only the name (as character) instead of the
> data.frame
How can I fix it?
I usually use lists for such cases,
> but (1) in the real thing, it gets complicated with the names and structure
> (because I want to save lists with 3 dimensions instead of simple
> data.frames,
> as in this example) and (2) I prefer saving each list separately (and I

I'm not sure I'm really clear

Thank you in
