[R] Why using hist when setting the parameter probability=TRUE does not create probability plot?

Hi All,

When carrying out hist(samples,breaks=50,probability=TRUE), the column
values are considerably greater than 1, which seams very unreasonable. The
plot is attached.

I think the column value of the hist plot should correspond to
x$counts/sum(x$counts)
   (x=hist(samples,breaks=50,probability=TRUE)). The size of data is a
little bit larger,  causing failure of uploading. If you need the data, I
can email it to you.

Can anyone help me?

Thanks!

Best regares,

Huaping Wan
