R help - Aug 2012 - Calculating percentages across multiple columns

I have the following data and am trying to find the percentage of bid
values purchased for that price.

So let's say I have a bid of 5 and it's sold 2 times for $3 and $5.
Since
the original bid was $5, the
percentage of times that that bid value results in a sold purchase AT that
specific bid level was
1/3 because of the three time where the bid was three, it ended up being
sold for $5 one time.

So I'm wonder how to generate that info in R. The percentage of a bid being
sold at the same purchase
price. Can anyone point me in the right direction.

f = data.frame(bid=c(3,5,5,8,3,5,4,2,3,5), purchase=c(6,3,4,5,5,5,6,2,3,7),
               sold=c(0,1,0,0,0,1,1,0,0,1))
f


Thanks.

Your question is very unclear.Can you provide a better question or at
least a column of outputs you expect and an example with the dataframe
you provided?
