Dear List,
some days ago my R started to regularily freezes, especially during
these operations:
mso(,permutations=999), package vegan
anova.cca(), package vegan
forward.sel(), package packfor
I am running R on a 64-bit Windows 7 installation, 4 cores, 8 GB RAM.
I just today updated R to 3.2.3, all packages, and R-Studio to their
most recent versions.
Still the error persists.
Two things are strange:
All these functions (and more) have been working without any problem for
2 years.
The freezes occur at different points in the algorithms. For
forward.sel(), a stepwise variable selection process
in species distribution modelling, the system fails at different steps
(say after variable 8 or 18), but inevitably fails.
R-Studio is still responsive meanwhile, but the "Stop"-Buttom does not
work, and the programm needs to be restarted.
Is there any way of troubleshooting or finding out who the culprit is?
Thanks.
