[R] SAS Macro Variable in R

[David Young]

Hi I'm new to R and would like to implement a SAS-like macro variable
in R.

What I'd like to do is take the simple R code below and change the
"=TEF" to different letters to refer to different companies' data for
download.

# DOWNLOADS FILES FROM YAHOO INTERNET
download.file('http://ichart.yahoo.com/table.csv?s=TEF.MC&a=00&b=1&c=2003&d=05&e=23&f=2009&g=d&ignore=.csv',
 'c:\\projects\\stock data\\data\\test.csv',quiet=TRUE)

As you can see the text I want to change is within the quoted Internet
address.  Is this possible in R?

Thanks in advance for any assistance.
