Hi, I'd like to clarify my previous posting. See below - my updates are noted with *s Thanks, Sarah Ordaz ord...@upmc.edu
Hello, I am a newbie to the lattice package in R, and I'm trying to make a plot using the xyplot function. I have repeated measures data (2 conditions) for two different groups of subjects (teens and adults). So far, I've made a basic graph using xyplot(y ~x, group=subnum, data=mydata, type="b"). *y is cognitive performance *x is pupil diameter *subnum = subject number *agegrp = age group (either teens or adults) *Here is "mydata", a sample data set: subnum agegrp condition pupil(x) cognitive(y) 101 T A 5.4 97 101 T B 4.4 98 102 T A 3.1 88 102 T B 4.9 95 103 A A 5.3 75 103 A B 4.2 83 104 A A 5.8 84 104 A B 6.1 65 Now I would like to make all the teens' lines one color and the adults' another. Additionally, I'd like to reformat the dots so that the points referencing condition A and condition B are different. Can you help me with this? Thanks!
