How about, d<-density(rnorm(10000)) plot(d) wvs <- which(d$x > 1 & d$x < 2) polygon(d$x[c( wvs[1], wvs, wvs[length(wvs)] ) ], c(0, d$y[wvs], 0), col = "bisque")
Georg Otto a écrit: Hi, if I plot a normal distribution like this: d<-density(rnorm(10000)) plot(d) how can I highlight the area below the graph in a certain interval, say x=1,2? I understand that I should use polygon, but I have not found the right way to give the result that I want. Thanks a lot!
