Dear R,

The glmulti package no longer loads through the library() command, apparently 
because of a problem with rJava.
I have today reinstalled R from scratch (updated to v2.14.0) and reinstalled 
all packages from scratch and updated them all too. The problem is the same as 
I found on v2.13.2. See session below for the error. I tried
install.packages(rJava) as advised by the error report but it didn't help (see 
session below).

Please read more carefully:

"Try re-installing Java and make sure R and Java have matching architectures."

It does not ask you to reinstall *r*Java but to reinstall Java.

Have you done that? So which architecture is your running R version and which architecture is your Java version?

Best,
Uwe Ligges







Any advice would be much appreciated: I can now not use glmulti at all and I 
can't see how to solve this!

Thank you very much R Help!
Best,
Toby
