Running R from a CD on Windows?
There is a batch script, rgui.bat, in batchfiles, see home page at batchfiles.googlecode.com, that will search the registry and a few other places for R and start up R if it can find it. It does not search CD's automatically but that would be simple to add. On Dec 27, 2007 3:25 PM, Charles Annis, P.E.

Greetings, R-ians: Yes it's easy to run R from a CD: I copied my windows installation folder to the CD, then copied my R working directory to the CD. To run from the CD, I copy the working directory from the CD to the desktop, and then create an R desktop icon that points to Rgui.exe on the CD, and starts in the working directory folder I just copied to the desktop. The problem is that to create the desktop R icon you need to know that Rgui.exe is on the CD in the bin subfolder of the R-2.6.1 folder, which I know but the person being introduced to R for the first time does not. And creating a desktop icon is busywork that some find annoying. And then the user needs to copy the basic working directory folder to the desktop, since R needs to be able to write to it and writing to the CD can't work with a write-once CD. Alas, my uses just want to put the CD in the drive and have the autorun facility take care all this: 1) If there isn't a folder named "R-project" on the desktop, copy the one on the CD to the desktop. 2) Create a desktop icon for R that points to Rgui.exe on the CD. The installation must determine what drive is currently being accessed, since "D:\R-2.6.1\bin\Rgui.exe" would only work if the CD was running from drive D. 3) Have the icon Start in "desktop\R-project" which is legal if you create the icon yourself, but apparently not legal to put on the CD since the windows are erased and cannot be filled in if the icon is copied back from the CD to the desktop. Since the basic R installation on Windows can create a desktop icon, I know this must be possible. I would be grateful for any help. Thanks Charles Annis, P.E.
