Following the other suggestions, I did not notice mention of another trick for slimming down graphs of many points. viz. Do not plot points that substantially overlap: > xx <- rexp(1e05) > qq.results <- qqnorm(xx, plot.it=FALSE) > qq.slim <- unique(round(as.data.frame(qq.results),3)) > dim(qq.slim) [1] 10233 2 > plot(qq.slim) > Choose the digits arg in round to be large enough to allow for points that do not overlap to be seen and small enough to slim down the number of plotted points. In the example above, 10233 vs 100000. HTH, Chuck -- Charles C.
