The problem is barplot. To see that : R> (barplot(dpois(0:45,20),xlim=c(0,45),names=0:45)) R> axis(3) Try something like : R> plot(0:45, dpois(0:45,20), type="h", lwd=4, col="gray") R> curve(dnorm(x,20,sqrt(20)),from=0,to=45,add=T) Romain -- visit the R Graph Gallery : http://addictedtor.free.fr/graphiques ~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~ ~~~~~~ Romain FRANCOIS - http://francoisromain.free.fr ~~~~~~ ~~~~~~~~ Doctorant INRIA Futurs / EDF ~~~~~~~~ ~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~ ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
