object names from character strings

I realize this is probably pretty basic but I can't figure it out. I'm looping through an array, doing various calculations and producing a resulting data frame in each loop iteration. I need to give each data frame a different name. Although I can easily create a new character string for writing each frame to an output file, I cannot figure out how to convert such strings to corresponding object names within the R workspace itself, so as to give each d.f. a distinct name. The closest I got were various attempts with the as.name function, but couldn't get that to work either. Any help appreciated. Thanks.
Here's the first example in the help(assign) page:
or(i in 1:6) { #-- Create objects 'r.1', 'r.2', ... 'r.6'
nam <- paste("r",i, sep=".")
assign(nam, 1:i) }
ls(pattern = "^r..$")
