Prof. Ripley, thanks for the pointer. I should review the Windows FAQ
more often, despite essentially not using it any longer.

I think that there is a typo in the second sentence in that FAQ:

...so you can burn an image on the R installation on your hard disc...

looks like it perhaps should read:

...so you can burn an image _of_ the R installation on your hard disc...

Best regards,
