[R] How to plot PDF which is in the form of orthogonal polynomial

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

Hi, there. Does anybody know how to plot a smooth density plot for some data simulated from certain distribution? Thanks. Yulei $$$ Yulei He 1586 Murfin Ave. Apt 37 Ann Arbor, MI 48105-3135 [EMAIL PROTECTED] 734-647-0305(H) 734-763-0421(O) 734-763-0427(O)

Hi, In the first place I was wondering if there are no function _insert.vector_ in base. Thanks Peter and Gabor even for the bad news. E. Peter Dalgaard wrote: Witold Eryk Wolski [EMAIL PROTECTED] writes: Hi, How to add values to an array at any position. Asking because of the following:

RE: [R] How to plot PDF which is in the form of orthogonal polynomial

I am not sure that I understand very well what you want to do but you might want to try 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() Francisco PS: I reccomend you to read
