[R] lme: object is not a matrix

Dear all, when running in R a simple lme call (3 variables in data set) which works perfectly fine in S-PLUS, I keep getting the error message " Error in model.frame.default(formula = ~t + can2p + code, data = list( : object is not a matrix" Any help would be very much appreciated.
