My organization has a policy against "installing software downloaded from the Internet." There is a waiver procedure, but it is difficult and lengthy. It is much easier to get approval to purchase software, even if it is a CD copy of open-source. However, a search on r-project.org didn't seem to show any way of obtaining the distribution in this way. Any clues would be

It is meant as a general overview rather than as detailed instruction. For example, something like the following sequence of commands. At lecture time, I want the interpreter to read these commands one at a

Hello - Have both astronomic and geodetic data sets with values in the form "ddd:mm:ss.sssss", where dd is an integer between -180 and 180, mm is an integer between 0 and 60, and ss is a floating-point number between 0 and 60.0. In order to do anything useful with these values they need to be turned into their "decimal degree" equivalent. Assuming the data is a vector y, the
