Dear list,

I have a set of 100+ variables. I would like to have one by one crosstables for each variable. I started with
table(variable1, variable2)
table(variable1, variable3)
table(variable1, variable4)
...
table(variable2, variable3)
table(variable2, variable4)
...

It seems rather tedious.

Any better ideas around?

Thanks for any help!

you can use combn to create the combinations and the following will
create a list of all the results:

x1 <- x2 <- x3 <- x4 <- 1:10
comb <- combn(c('x1','x2', 'x3', 'x4'), 2)
myTab <- lapply(seq(ncol(comb)), function(x){
    table(get(comb[1, x]), get(comb[2, x]))
})
# put names of the combinations
names(myTab) <- apply(comb, 2, paste, collapse=":")
