Edit Question
Title
Body
I have two data.frames. For examples sake let's say they look like this: df1 <- data.frame(x=rep(letters[1:26], 16)) df2 <- data.frame(y=letters[1:4]) What I would like to do is subset 'df1' to contain the rows whose first column value matches any value within the first column of 'df2'. Now, I've tried: subset(df1, df1$x == df2$y) But this tells me that I need equally sized data.frames. Thoughts?
