Hi Ajish,
Apologies for the confusion. Kasper's suggestion should get you
going. Actually, I believe getBioC will also work, just leave out the
develOK=TRUE argument.
In the past, the installation scripts allowed any version of R and any
verison of Bioc. This led to much confusion because R version and
Bioc releases are in lock-step.
We will add some documentation for How To Install Devel Packages.
Best,
+ seth
