I am having a problem with the installed R 2.12.0 on 32-bit Windows XP machine using the binary version.
The installer I am using is R-2.12.0-win.exe . The problem I have is that some
of my installed packages will not load, in particular PolynomF, which has a
pre-compiled .dll. Other packages such as SOAR, which is pure R, attach and
work without a hitch.
The error message I am getting when trying to load PolynomF is a question
whether or not the package has been compiled for the present architecture.
(This package works without a hitch on R-2.11.1, for example.)
Is there any significance in the name of the installer now including just "win" rather
than "win32", as it was in the last release?
Is it the case that all packages will have to be re-built for the present
release?
Generally packages do need to be rebuilt for new versions of R (other
than patch releases, where only the last digit changes). R 2.12.0
supports both 32 bit and 64 bit Windows in the same installation, and
since Windows doesn't have MacOS-like "universal" binaries, that means
binaries need to be put in the right place. Generally that's an i386
subdirectory for 32 bit, and an x64 directory for 64 bit.
I don't know why a 32 bit DLL wouldn't work with 32 bit R 2.12.0, but if
it was installed for 2.11.1, it might not be in the right place.
