built-in editor underlining

Hi JiHO,

In general there are 3 ways of achieving this 1) part of R.app, as  
the current internal editor, 2) part of an existing editor that  
supports this kind of functionality like BBEdit/TextWrangler and  
TextMate, or 3) editors that do not support executing AppleScript or  
Perl/Bash/Python directly.

For those editors, e.g. Smultron and SubEthaEdit, I have used a  
product like iKey, which allows you to define a global 'hot' key that  
activates AppleScript for you. In those cases it is not good to use  
Command-E for source file as this is used too often. I tend to use  
F12 and Command-Return for source
file and execute selection.

I rarely use the internal editor for the very few cases where R.app  
still crashes (at the moment I see that only with certain Lattice  
graphics when I make them full screen). Unfortunately you then loose  
the function prompt (which I still use on the R Console, but is more  
typing). On the other hand, you do get project file grouping,  
multiple syntax definitions and a recent example Byron Ellis gave for  
TextMate, the ability to build a package from within a project. I  
think that kind of extensibility is extremely useful.

One thing which make using R.app built in editor very comfortable is
the ability to send code to R using CMD+E and CMD+ENTER. Do you
emulate these functions in BBEdit? If yes how? I would really like to
be able to use an external editor also, just for consistency between
my different projects. Smultron is my editor of choice and it has R
syntax highlighting but I don't know how to emulate these functions
in it.

Depends. If you found your perfect editor and it integrates
seamlessly, sure there' is no point in using the integrated one.
However, that doesn't mean that we should keep it as plain and basic
as possible. Especially with features that leverage R itself it can
be more useful if it has additional features - and this is harder for
other editors to do, so we should take advantage of it.
