[R] Unable to require installed package

[Uwe Ligges]

1. You need R version >= R-2.12.0 on Windows in order to use a package 
that is compiled under R >= 2.12.0.
2. winbuilder gave some reports. That may have said if and why your 
package could not be compiled under 64-bit R for some reason.
3. If you have a 32-bit-only package, you can only load it in it in an 
32-bit R instance, not in a 64-bit R.
4. 32-bit R runs fine under 64-bit Windows.

Best,
Uwe Ligges
