Not being the expert I have looked at papers like 'simpleR { Using R for Introductory Statistics' by John Verzani. Some sample Code is in these papers. Looks like I have to search for ideas to code a programming language like Java by taking input from R(r-java). Can R be used directly to hit web url's based on distributions that these functions generates ?
?rnorm ?runif ?rgamma ?rexp I also realize the work 'Simulation' means simulation of queues or other simulation experiments. Law's book on simulation ? This is about generation of traffic.

I'm sure Rui would be happy to get a small consulting fee to show you how to do it in one line of R code. -- David. > > Mohan > > > > > -----Original Message----- > From: Rui Barradas [mailto:ruipbarra...@sapo.pt] > Sent: Wednesday, June 27, 2012 4:11 PM > To: Mohan Radhakrishnan > Cc: r-help@r-project.org > Subject: Re: [R] Simulating web requests > > Hello, > > Homework? > There's a no homework rule but see inline. > > Em 27-06-2012 10:20, Mohan Radhakrishnan escreveu: >> Hi, >> >> I am looking for some assistance with these requirements. > We >> are trying to simulate web requests to hit a web applications.
