The hist() only allow the overlay of two histograms, and although barplot() allows beside=TRUE, it does not show frequency values (like hist) but rather all of the values.

Hello all I am wondering how rails handles case sensitivity in databases. If I do a Person.find_all_by_name("tim") in mysql I would expect to get tim, TIm, and Tim. Do I only get tim in postgres?
