R is quite a powerful environment. Here's a small way it could be even better.
I wanted to change the working directory, so I tried the obvious thing
> cd("foo")
Error: couldn't find function "cd"
Then I looked for `directory' in the FAQ but found nothing. A search
for directory in the introduction also turned up nothing.
A Google search for "gnu R change directory" brought up a link to the
Windows FAQ, and there was the answer: setwd. Oddly enough, setwd is
not mentioned in the general FAQ, the introduction, or the language
definition.
Hopefully someone can add a mention of setwd to the general FAQ or the
intro. Even better would be to have a cd() command, since that's what
almost every beginner will try first.
