Subject: How to use tapply with more than one variables grouped
In-Reply-To: <6E8D8DFDE5FA5D4ABCB8508389D1BF88D5B389@SRVEXCHMBX.precheza.cz>
interTable <-data.frame (Tapply ($ contb_receipt_amt date, list ($ cand_nm
date, $ contbr_st date), sum))
I got create a table with the sum total contribution (contb_receipt_amt) of
each presidential candidate (cand_nm) in each state (contbr_st). How could
from interTable create a table of states where candidate 'Obama' has
received greater Contribution?
thanks
