Problem with R >3.0.0

What is bicor()? From the WGCNA package? Perhaps the package is doing something incompatible with the long vector support in R 3.0.0. You need to report such queries to the maintainer.

The maintainer is reporting for duty :)

The version of WGCNA currently on CRAN uses .C to call compiled code.
If I read the manuals right, long vectors are not allowed in .C calls.
In my .C calls I use explicit type casts (as.integer, as.double etc)
for all arguments.

Once we see a reproducible example, we can figure out the problem.
