hist(x, ...) with normal distribution curve
Hi answered hundered times.
Dear R people: I would like to superimpose a normal curve on a histogram.
x<-rnorm(150) h<-hist(x,breaks=15) xhist<-c(min(h$breaks),h$breaks) yhist<-c(0,h$density,0) xfit<-seq(min(x),max(x),length=40) yfit<-dnorm(xfit,mean=mean(x),sd=sd(x)) plot(xhist,yhist,type="s",ylim=c(0,max(yhist,yfit))) lines(xfit,yfit) Bill above is e.g. Bill Simpson's answer from 2001. Found from R-site search ***histogram density normal***. HTH Petr

. I am looking for a histogram or box plot with the adding normal distribution curve I think that must be possible, but I am not able to find out how to do. Regards Knut
