[R] questions for hist()

[Donghui Feng]

Dear all,

I'm creating a histogram with the function hist(). But
right now what I get is column representation (as normal).
I'm wondering if I could switch X-axis and Y-axis and
get row-representation of frequencies?

One more question, can I define the step of each axises
for the histogram?

Thanks so much!
