Not really. The incantation is "R --gui=tk" or "gnome" or "X11" but
the two former are quite sketchy (proof of concept, really). The last
one is the default, but not with menus etc., just windows for graphics.

Any shell command can be executed via system(). This is in a subshell,
so of course cd has no effect on return: look up setwd()

Not in any "standard" way AFAIK. There is a number of ways you could
create your own convention (e.g. via environment variables), though.

Depends on what you want to do. There are quite a few documents around
with example code and several books have their scripts made public.

In general, do your self a favour and read at least the Intro and
Admin manuals from.
