[R] correlation b/w a continuous variable and a categorical variable

Dear Listers: I happen to have this question in mind, is there a way to evaluate the correlation between a continuous variable and a categorical variable (without discretizing the former)? My intuitive is using lda by considering the latter as response variable but not sure. thanks, weiwei --

I see. i think the question is, I did not have a clear idea of the correlation between them (if I insist no transformation). Otherwise, for a binary variable case, maybe a simple one-way t-test serves the purpose if I defined such correlation or dependency as the group mean difference. thanks.
