Re: [R] Plotting two qqnorm plots:

You can do this in lattice: library(lattice) df = data.frame(val = rnorm(100), group = rep(c('x', 'y'), each = 50)) qqmath(~val, groups = group, data = df) Hope that helps, Greg njhuang86 wrote: Hi all, Does anyone know how to plot overlapping qqnorm plots on the same window? Suppose I have
