[R] testing independence of categorical variables

[Shoaaib Mehmood]

hi,

is there a way of calculating of measuring dependence between two
categorical variables. i tried using the chi square test to test for
independence but i got error saying that the lengths of the two
vectors don't match. Suppose X and Y are two factors. X has 5 levels
and Y has 7 levels. This is what i tried doing

>temp<-chisq.test(x,y)

but got error "the lengths of the two vectors don't match". any help
will be appreciated
