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
where I did wrong.

Thanks.
