This way the R is programming environment and language so more or less even newcomers are expected to do some programming. And it is also volunteer project. I expect that renaming columns is task which is not done very often, so there did not come up anybody who was interested in programming such function. Also the pool of available functions seems to be quite extensive in base R and even bigger in all available packages. Sometimes is hard enough to remember correct function name. There is also excellent help and manual pages with nice copy/paste feature examples. I wonder if you ever tried to get some help from e.g. Excel help. Quite often you are completely lost. > functions used will also be more efficient and better designed than > the typical new user. If a new user does not wont to use command line syntax he/she can use some of available GUIS (see R GUI in home page) e.g. JGR.
