cartesian product with dplyr R

Question

I\'m trying to find the dplyr function for cartesian product. I\'ve two simple data.frame with no common variable:

x <- data.frame(x=c(\"a\",\"b\",\"c\"))         


        

Answer 1

expand.grid(x=c("a","b","c"),y=c(1,2,3))

Edit: Consider also this following elegant solution from "Y T" for n more complex data.frame :

in short:

expand.grid.df <- function(...) Reduce(function(...) merge(..., by=NULL), list(...))
expand.grid.df(df1, df2, df3)
