When you set prob=TRUE you get a ***density*** scale. The resulting
histogram represents a probability densit
Hi,
I am having a new problem that how I can set the probability scale
from 0 to 1 when I using on probability scale. Sometimes I get the maximum
probabilty more than 100%.
Thanks!

What's wrong with ``hist(samp,prob=TRUE)''?

?truehist in library(MASS)?
library(MASS)
truehist(samp)
x <- seq(-8.5, -6, length=51)
lines(x, dnorm(x, mean(samp), sqrt(var(samp
This just worked for me in both S-Plus 6.2 and R 1.8.1.
hope this helps. spencer graves

Hi,
I am facing the problem that I want to plot a histogram chart set
freq to true and overlay with normal or weibull or exponential distribution
curve.
The sample code is shown as below:
>samp<-c(-8.2262,-8.2262,-8.2262,-8.20209,-8.09294,-8.07321,-8.07321,
-8.07321,-8.0717
