Re: [R] Ask for histogram

If I do b <- rnorm(4332) hist(b,probability=T,breaks=30,col='lightblue',ylim=c(0,1)) rug(b) The plot looks entirely reasonable. As far as being different from SAS, perhaps SAS and R use different breakpoints, that is, different boundaries between the histogram bars. -Don At 11:58 A

[R] Ask for histogram

Hi, I use a vector of data to draw the histogram, but it is different from the graph by SAS. Can you check it for me please? b is a column vector of 4332 hist(b,probability=T,breaks=30,col='lightblue',ylim=c(0,1)) rug(b) When I used rug, I find the records are smaller than 4332. I don't know w
