Physical Units in Calculations
Back in 2005 I had been doing most of my work in Mathcad for over 10 years. For a number of reasons I decided to switch over to R. After much effort and help from you folks I am finally "thinking" in R rather than thinking in Mathcad and trying to translating to R. Anyway, the only task I still use Mathcad for is calculations that involve physical quantities and units. For example, in

Trouble installing packages on R2.14.1
Hi, Have just recently downloaded R version 2.14.1 and can't install packages (Code below), 32bit version on windows. From the looks of things access is the problem but I don't know where to start, would it be my system that is the problem or is the repository not set up for the latest version yet? Any ideas on how to rectify the problem would be greatly appreciated Cheers >
