[Rd] R 3.0, Rtools3.0,l Windows7 64-bit, and permission agony

[Kevin Coombes]

Here's the short answer:  Whatever you used to do should still work.

I started this thread, not knowing that it was going to get sucked into 
a whirlpool on the fringes of an operating system religious war.  My 
sincerest apologies to everyone who has gotten confused as a consequence.

I only ran into problem because I installed R 3.0 and Rtools 3.0 on a 
new machine, and accidentally put Rtools in a different location from 
where it used to reside on the machines I used for R 2.whatever.  And so 
the scripts I used to build packages no longer worked because the path 
was wrong. If you can avoid doing something silly like that, then your 
old methods for building and maintaining packages should work the same 
way they always did.
