Dear all, here is a simple problem that surely you already come across, but is giving me a big headache... I have a dataframe like this: set.seed(3) mydata <- data.frame(var = rnorm(100,20,1), temp = sin(sort(rep(c(1:10),10))), subj = as.factor(rep(c(1:10),5))) and I need to make a scatter plot for each subj, not a problem, but... what i want is to
