Dear All,
Thanks everyone for your kind responses.
Now I understand what is gong on! I guess that the question asked is
wrong in the first place.
As there is a categorical list of groups and their values (a range of
pipe diameters and a flow for each diameter), and a barplot would be a
suitable tool to use.
However, it also means that I cannot plot probability density curve
using this type of data because I would need to have a histogram
instead. Did I get it right?
Many thanks,
Olga

Dear all,
I am making a barplot as following:
barplot
(c
(1,2,3,5,2,3,1
),names
.arg
=
c
("100
","200
","300
","400","500","600","700"),xlab="diameter",ylab="flow",main="some
title",space=0.1)
I am also trying to add a probability density curve, however using
lines(density(c(1,2,3,5,2,3,1))) does not give a desired result.
