I think there is no other way. Furthermore, the fact that >you can do this is really a key advantage of open source. But that is the solution to a different problem. Reading the source for merge tells you how R merges two dataframes, the beginning user wants to know how to link together the information s/he has in two files but does not know what the name of the relevant command is, or indeed whether it is even possible. To give you some idea of how ignorant some of us are it was only quite recently that I realised (despite several years reading free documentation, books on R and R-help) that if I type cor at the prompt what I see looks like source code but is not _the_ source code.
