Hi Gabor,
Thanks for the code, it's what I was looking for. The route I was
thinking about was to use, based on your code, the names from
my.data.frames as a pointer to the actually dataframes.
I was envisioning something like
a <- data.frame(1:10)
b <- data.frame(10:1)
c <- data.frame(letters[
You might want to have a look at the plyr package -
http://had.co.nz/plyr. The intro pdf describes a couple of problems
that are similar to yours.

I think you need to be a bit more specific on this one.
What is the format of your data.frames? On disk or actually in your
workspace?
Example code would also help. Even psuedo code describing what you
want to do.

Hi all,
Wade, from your description it is not clear to me whether you have
fifty _R objects_ or fifty files containing tables (i.e. data frames).
If the former, you can do something like
a <- data.frame(1:10)
b <- data.frame(10:1)
c <- data.frame(letters[1:20])
my.data.frames <- data.frame( name=c("a", "
Hi all,
I have roughly fifty dataframes and a dataframe with the names of the fifty
dataframes. I want to perform the same set of manipulations on all fifty
dataframes, but can't find a way to batch process from a list with the
dataframe names using a loop. Is there a way to read the file names f
