Dear R-ers:
I'm sorry to disturb you, I want just ask if R can plot a given
complicated density function. I mean if we have the expression of the
density en we want to see how it's look like? and this is a density
with two variables thus it's a 3D plot
Thank you very much

Dear R-ers:
I'm sorry to disturb you, I want just ask how to work with a sum?
To be more exact I want to work with the function
f(x)= sum_1^{n}K(x-x_i/h), K is a kernel or any other function
I have a data set (x_i) and I want to compute x for each x or plot
f(x).
Thank you for your hulp
