memory problems when combining randomForests
Dear all,
I am trying to train a randomForest using all my control data (12,000 cases, ~
20 explanatory variables, 2 classes). Because of memory constraints, I have
split my data into 7 subsets and trained a randomForest for each, hoping that
using combine() afterwards would solve the memory issue. Unfortunately,
combine() still runs out of memory. Is there anything else I can do? (I am not

choose() function returning anomalous results (zero instead of one)
...g choose(3,3) as 0, instead
of 1. It does not do this consistently - I've put the simplest code I've
been able to use to consistently generate the problem beneath my sig.
Something about the loop seems to generate the problem. If I remove the
loop over Q, and just set Q = 3, then choose(Q1,testn) (where testn is
equal to the nn shown above) works without a problem.
I'm not sure if it's related, but I'm also having problems with browser()
not firing the first time through and/or having code continue to execute
before it interrupts, i.e.:
------

[LLVMdev] Fail to build dlls with visual studio 2010 x64
Hi,
I can build LLVM just with VS2010 x64. However, when I try to build it with
-DBUILD_SHARED_LIBS:BOOL=true option, it seems to fail with a lot of
unresolved external symbol. Is it a known issue? Is there anyway to fix it?
Thanks,
