Dear Splus user,
I am working with Splus Version 6.2.1 for Sun SPARC, SunOS 5.8, 64-bit
: 2004
and i am surprise with the results of the following command:
> hist(rnorm(20, mean=.5,sd=.1), probability=T, plot=F)
$breaks:
[1] 0.35 0.40 0.45 0.50 0.55 0.60
$counts:
[1] 2 5 3 7 3
why counts are not probabilities ?
When the variable to display doesn't range between 0 and 1, the results
of counts
are probabilities:
> hist(rnorm(20, mean=.5,sd=.1)*100, probability=T, plot=F)
$breaks:
[1] 30 35 40 45 50 55 60 65
$counts:
[1] 0.01 0.02 0.01 0.04 0.03 0.05 0.04
Is there good reason for this ?
Many thanks for your answers.
