density(). There are some good examples for this function under example(density). The result is an object with class "density" that you can plot directly using plot()

Subject: [R] How to plot PDF which is in the form of orthogonal polynomial Date: Sat, 30 Oct 2004 11:19:16 -0500 (CDT)
Dear all
using the orthogonal polymial on a set of data, I get an approximate density which basically is in the form: exp(-polynomial),
as you know, the parameters are the converged coeeficients.
obviously, It is hard, if not impossible, to use the inverse CDF method to get a sample and then plot density. then how can I plot the approximated density in order to have a graphical comparision with the real data's histogram.
any hint is appreciated
thanks
