Will something like this work?
x <- data.frame(xx=c("r1", "r2", "r3"), yy=c(1,2,3))
y <- data.frame(aa=c("R1", "R2", "R3"), bb=c(10,12,

Try:
col1
I have two data frames. Suppose the first has rows
r1
r2
r3
and the second has rows
R1
R2
R3
I'd like to generate the data frame:
r1 R1
r1 R2
r1 R3
r2 R1
r2 R2
