Hi List, I have run R from Windows Terminal server and it works fine. I now need to install it on apache Web server / Amazon EC 2 server to test R (with a GUI) for computing on a cloud (using a framework I wrote about).Intent is to benchmark R 's superior algorithms on very big files > 1-2 gb (against mainstream s software) Also is there any data compression /encryption technique or package in R. Intent is reduce bandwidth transfer time and costs. Regards, Ajay decisionstats .com [[alternative HTML version deleted]]
