Hi... I'm still a beginner in R. While doing some curve-fitting with a raw data set of length 22,000, here is what I had:



> hist(y,col="red")

gives me the frequency histogram, 13 total rectangles, highest is near 5000.



Now

> hist(y,prob=TRUE,col="red",ylim=c(0,1.5))



gives me the density (probability?) histogram, same number f rectangles, but the highest rectangle is obviously higher than 1, how can this be?!!!



And it gets worse, if I use the 'breaks' option, when I add 'breaks=1000', many of the rectangles were higher than 2.

What am I missing here?



Thanks.


P.S. I had to post this thread via email as it got rejected as I posted it from Nabble, reason was "Message rejected by filter rule match"
