Cygwin and Rtools (Was: RE: [Rd] cygwin tar?)

[Henrik Bengtsson]

If it helps anyone, below is the startup script I use in WinXP to get
an MSDOS prompt that give me access to R and Ripley's Rtools so that I
can run RCMD build etc without problems and at the same time keep my
Cygwin installation. This is pretty much what Ripley suggest. Note the
"NOTE: ..." below!

I'm sorry if mine or your email client cuts the lines.

rem # Usage: RCMDprompt.bat [path]
rem #
rem # This script opens a MS-DOS prompt with a enviroment variables
rem # set such that R can be ran and packages can be build. 
rem # If 'path' is given, the working directory will be set
accordingly.
rem # 
rem # NOTE: This scripts works even if Cygwin is installed. HOWEVER,
you
rem # can not have any Cygwin applications running (not even a shell
or
rem # XEmacs for Cygwin) at the same time you try to run RCMD.
rem #
rem # Requires:
rem # To build and install packages two things must be installed, i.e.
rem # exists in the PATH. First, the Rtools compilation [1] by B.
Ripley 
rem # must exists. The path (R_TOOLS) to it is set below. Second, Perl

rem # (must not be Cygwin/Perl) must also exists. The path to it is
set
rem # below.
