a question about "multilevel"model
This is reshaping the data frame from wide to long form. In particular, MULTDV is as.vector(t(dvs)). Try typing this on a line by itself: make.univ to see the code and clarify your understanding. Also try the examples in ?reshape to familiarize yourself with wide to long transformations.

Hello all: I've read the document named "A Brief Introduction to R, the multilevel package and the nlme package". At p68, one can transform the dataset to the required format by using "make.univ". I wanna know,how the new variable "MULTDV" is calculated(can you show me the formula if possible please?)?And what's the usage of this new variable in the following analysis? Thanks a lot! My best. ? ? ? ?[[alternative HTML version deleted]]
