Hi everybody, well, I definitely don't understand anything. Why the hist function with freq=FALSE gives such a strange result??? R <- c(-1.10, 0.79, -1.17, -0.53, -0.26, -0.22, 0.29, -0.26, -0.26, 0.39) hist(R, freq=FALSE, breaks=10) Thanks everybody [[alternative HTML version deleted]]

It looks like each of your bars is about .2 wide; area = height*width, so .... that high one in the middle has area of about 2*.2 = .4 HTH Peter Peter L.

Y-axis in your code is ``Counts'' irrelevant to probabilities.

Hi everybody,
well, I definitely don't understand anything.
Why the hist function with freq=FALSE gives such a strange result???
R <- c(-1.10, 0.79, -1.17, -0.53, -0.26, -0.22, 0.29, -0.26, -0.26, 0.39)
hist(R, freq=FALSE, breaks=10)
Thanks everybody
