R is not a very good macro language... I recommend against this strategy.
We could be more concrete in offering alternatives if you were a little more complete in your reproducible example . What variations exactly were you thinking of? What kind of data are you working with? The way you read in the data can make a big difference in how effectively you analyze it. (Not asking for your actual data... just a fake version of it.)
