[R] Numerical Integration

[Feng Zhang]

Hey, all

Now I am using EM algorithm to do some
optimization. Within that E-step, I have to
calculate some multivariate integration
given some parameter values Theta and function form
of a probability density function f.

So I want to know if there are some package
in R to do such numerical integration given such
function form and parameter values?

Thanks for your kind support on this.

Have a nice day!

Fred
