[R] Scripting capabilities for R

[Jim Lemon]

A bit tardy, perhaps, but here is an NEdit macro for Linux that will
display help
on a selected keyword in an R command file that is being edited.

Select Preferences|Default Settings|Customize menus|Macro menu..
Define a New macro named, for example, R help
Copy the attached macro into the macro editing window at the bottom
Edit the macro by uncommenting the appropriate lines and changing the R
home
directory
Apply the macro
Highlight an R command in the editor and select Macro|R help

You should be able to get either HTML or "text" help in a separate
window.  I
welcome any comments and suggestions.

I have worked out a way to submit selected commands from NEdit to R via
batch
mode, but it is really clunky and I'll refine it to run in the R window
if
possible.  Stay tuned.
