Yep, that's a memory problem. If you are running under Windows, you can
make sure that you have enough memory allocated to R by using the
command line flag --max-mem-size=1G (substituting the correct amount of
RAM). If you have already allocated all your memory, then you have to
get some more RAM.

I am receiving an allocation error while using different expression
(MAS5 and LiWong).  This is happening during varying runs of a
The actual errors are shown below.

I'm not sure if this is a memory problem (I should have plenty of
or a BioConductor problem.

Any suggestions?  Thanks!
