batchfiles 0.4-1 consists of a set of Windows Vista .bat and other scripts used as front ends to R CMD ... and for other purposes.

Whereas Version 0.4-0 of batchfiles eliminated the need to set any paths when running R, version 0.4-1 now eliminates the need to set any paths when building and installing R packages. It does this by using the registry to find R and rtools and uses a heuristic to find MiKTeX (since MiKTeX does not have a reliable registry key) and temporarily sets the path to include rtools and MiKTeX.

Version 0.4-1 also includes an rtools.bat utility which will set the paths for that session that would have otherwise had to be set in case you want to use rtools and MiKTeX with other programs -- this is not needed if you only want to use R or if you only want to build and install R packages.

Also there is a new el utility (el.js) which runs the command given as its argument in elevated mode. e.g.

    el cmd
spawns a cmd session which is elevated.

The scripts Rcmd.bat, R.bat, Rterm.bat, Rscript.bat, #Rscript.bat, Rgui.bat, RguiStart.bat, Rjgr.bat are actually all the same script which query the name by which it was called to determine the appropriate action. These scripts are each self containd single file scripts which do not depend on each other or on other software. To install any of them just copy it to any place on your PATH and it can be immediately used. Uninstall by deleting it. Atlhough they query the registry they do not set the registry (except for Rversions.hta which calls RSetReg.exe, a program that comes bundled with R, that in turn sets the registry.)

Version 0.4-0 of these utilities and later have only been tested on Vista. Version 0.3-2 and earlier have only been tested on XP.
