Re: [R] data normalization

Hi, Probably you might have got the solution. Anyway, you can try this: Dat <- read.table(text=" ID  TIME    DV 1  0  0.880146038 1  1  0.88669051 1  3  0.610784702 1  5  0.75604 2  0  0.456263368 2  1  0.369991537 2  3  0.508798346 2  5  0.441037014 3  0  0.854905349 3  1  0.960457553 3  3

Re: [R] data normalization

assuming that the entries for each subject are ordered with respect to TIME and each subject has a measurement at TIME = 0, then you could use the following: Data <- read.table(textConnection("ID TIMEDV 1 0 0.880146038 1 1 0.88669051 1 3 0.610784702 1 5 0.75604 2 0
