Subject: match in dependence of 2 columns
In-Reply-To: <1360768766597-4658411.post@n4.nabble.com>
thank you, this code works:
library(plyr)
join(dat1,dat2,by=c("cu.nr.","name"),type="right")
but my dat2 frame has a lot of columns, which i don't want to match.
How can i say, that only the column "value" should be match to dat1 ?
Thank you.
Mat
