[R] Exactness of ppois

Hello, by checking the precision of a convolution algorithm, we found the following inexactness: We work with R Version 1.8.1 (2003-11-21) on Windows systems (NT, 2000, XP). Try the code: ## Kolmogorov distance between two methods to ## determine P(Poisson(lambda)=x) Kolm.dist - function(lam,
