Re: [R] lme: object is not a matrix

] lme: object is not a matrix Hi, make sure your data is in a data frame: Data - data.frame(t,can2p,code) just specify in which object you find those specific variables by using object$ before each one. I hope this solve the problem. If not, post your script, it's really hard to work

[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.
