Look at your first function: Grx<-function(x,r) { G0=Grx(x,0) G0=1; fu1<-function(t){exp(-t^2/(2*r*(r+1)))*Grx(x,r-1)} return(integrate(fu1,0,x)$value) } It immediately calls itself for infinite recursion. How did you expect to stop it? I would have expected some type of test before the call.

Hi, I wanted to compute the value of the function ifn at certain values of n. But I am receiving the following error when I was using the following code(given at the end). Error: evaluation nested too deeply: infinite recursion / options(expressions=)? I feel that since the function Grx is re
