Hello all, I need to perform the following integration where the integrand is the product of three functions: f(x)g(y)z(x,y)
the limits of x are(0,inf) and the limits of y are(-inf,inf). Could this be done using R? I tried using the function integrate 2 times, but it didn't work: z<- function(x,y) { } f<-function(x){ rr<-"put here the function in x" *integrate(function(y) z(x, y), -Inf,Inf)$value return(rr) } rr2<-integrate(function(x) f(x), 0, Inf)$value print(rr2) I didn't get any output at all!!!
