You mention Notepad++, I'm still using vi under cygwin and an ancient copy of
ultra edit.
When I was first learning Java and c++, the various commercial IDE
packages were great. However, I've found that with most things I end up
integrating
with bash scripts and end up in vi for "touch up" anyway- and if you take the
time to learn it many of the odd commands are quite helpful. IIRC many
of the IDE's offer language-specific help beyond syntax highlighting such as
signature suggestions as you type or menu options for compiling and debugging
that
pure text editors lack, not sure what the
R IDE does. I finally developed alt approaches for finding signatures and
it turned out to be easier to do this outside ide although sometimes I
compile bad code due to typo that IDE would have flagged.
In the simple case on windows, I vi my .R file and then invoke a script
to run it. In many cases ,the IDE menu's for more language specific actions
like compile and build are confusing and limited and have a learning curve
and there too I end up editing bash scripts using cmd line alt.
So, I guess my point is that I would not just run to an IDE for R or
others :)
