Dear all,

I have a surprising problem with the representation of frequencies in a
histogram.

Consider, for example, the R code:

b<-rnorm(2000,3.5,0.3)
hist(b,freq=F)

When I plotted the histogram, I expected that values in the y-axis (the
probability) varied between 0 and 1. Instead, they varied within the
range 0-1.3.

Have you got any suggestion for obtaining a correct graph with
probability within the range 0-1?

Thank you very much!

Bests
/Cristian/
