Greetings, I am new to R. Right now I'm most interested in the spaghetti plots of achievement over time by student ID associated with longitudinal analysis. How can I do a spaghetti plot of all students, but color the lines by group membership such as gender or race, and indicate this color scheme in the legend? Any advice would be much appreciated.
I do not think this is a Mac specific question, and I think you should read the r-help Posting Guide.
