Good afternoon, I'm trying to create a cartesian product in R with the letters of the alphabet. What I'm actually trying is this: First I create a matrix with the letters a <- as.matrix(seq(97,122,by=1)) Then I create a data frame with 2 columns with all the combinations b <- expand.grid(a, a) Finally I combine the 2 columns apply(b,1,paste,collapse=" ") The problem I have is that I can't find a way to transform those "decimals" to its Ascii character. I have tried several things like rawToChar and gsub unsuccessfully. Can somebody point me in the right direction? Thanks
