R help - Jan 2008 - Windows Shell Command under Vista

Dear R2008,

In Windows 2000, I used the following shell extension to allow right-click
rgui start in a directory (assuming rgui.exe is on the path:

-----
REGEDIT4


[HKEY_CLASSES_ROOT\Directory\shell\Run R] 


[HKEY_CLASSES_ROOT\Directory\shell\Run R\command] 
@="Rgui.exe --no-restore --no-save --internet2"
----

I switched to Vista this year. For reasons I don't understand, I have to
give the full path now, even if rgui is on the path. However, the solution
below does not really work, getwd() is always in \windows\system32. I tried
several cmd.exe "..." variations, without success (strangled by
"\""\"?) And
a nasty feature of Vista is the long delay of 19 seconds until a command box
comes up on my computer.

To avoid RTFMs: I know how to do this with setwd().

Dieter

--no-save
--no-restore"

Try this batch file which is in the devel svn repository of batchfiles:
http://batchfiles.googlecode.com/svn/trunk/RguiStart.bat

(Also see: http://batchfiles.googlecode.com)

Given a directory specified in argument 1 it will find R in the
registry (and look in a few
other places if not found there) and start Rgui.exe in specified directory.
This has the additional benefit that when you upgrade to a new version
of R you don't have to change anything.

How are you starting up the command line?  If I position myself to the right
side of the Windows Explorer window in Vista and press Shift-RightClick and then
choose Open Command Window Here then the command window
comes up instantaneously on my system -- there is no discernable delay
at all.

Same method for me (I only made it always visible to avoid the Shift). 19
Seconds on the first call, 11 Second later on a brand-new system. This is
Click-To-Visible time, processing starts earlier, when I start Sweave with 
short files it has finished processing before the box is on screen.
I normally start from scratch, so clicking .Rdata is not an option.

I have given up the shell approach, using AutoHotKey instead, which is
convenient since it picks the currently selected directory from Explorer and 
can also be used to start Sweave-make.

#Include ExplorerWindowControl.ahk ; << Defines Shellfolder
; This overrides Start/R which I never use
#r::Run,rgui.exe --no-restore --no-save --internet2, % ShellFolder()
