Re: [R] empirical null distribution

I'm using F-distributions :)
I allready found some things...I could plot the qqplot as you say and that gives me clear results.
Allthough I still want a clear graphic and I 'll explain it as good as I can...

I plotted 2 graphics

(the "disttest" is a distribution i simulated myself like this:
for(i in 1:100){


   vector<-c (X, Y, Z)
   vector2<-rep(c('X','Y','Z'),c(50,50,50))    data1<-data.frame(waarde=vector, soort = vector2)    library(mvtnorm)


   disttest<-c(disttest,summary(aov(waarde~soort,data=data1))[[1]][1,4])    }
(I want to compare the theroretical F-distribution with a distribution where
the variances are not equal...)

Thos are 2 fine plots but I just can't figure out how to put them together in one this possible in would make things much clearer because the window setting are not really equal wich makes it difficult to compare...

Thanks a lot allready!
