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.
