R help - Mar 2006 - "renaming" dataframe1 using "column" names from dataframe2?

I have a dataframe named ?temp?, and another dataframe
named ?descriptions?.

I wish to ?rename? temp, and to ?call? it the names of
a certain column in the dataframe ?descriptions?.

Is there a good way to do this?

A similar question:

I am using a ?for loop? to create several new
dataframes.
e.g.
for(j in 1:9){
..

I?d like each dataframe to be named d1, d2, d3, with
the number being tied to the j (the iteration).

Is this possible

?assign, but _don't_ use it; lists are better.
dfr <- list()
for(j in 1:9) {
  dfr[[as.character(j)]] <- ...
  }
Don't try to imitate the limited macro approach of other software
(e.g. SAS). You can do all that in R, but it's much simpler and much
safer to rely on list indexing and functions that return values
(rather than create objects).
