Re: [R] Superpose two QQ-plots (gamma distribution) with, lattice function qqmath()

David, Duncan, Hi Following on David's rate argument try (with modifications of pch and grid) rate - 1/4 shape = 8 rate = c(rep(1/4,100),rep(1/3,100)) I don't think the problem is related to the rate argument, which can well be vectorized, as is the case for a number of arguments in
