The current build report shows release failing on 32-bit windows


because the example is too large. The solution, and better practice, is 
to use more modest computation in the example.

Processing TCGA-AB-3009..
Error: cannot allocate vector of size 1.3 Gb
Execution halted

The devel build report


shows all builds failing because of use of an undefined object in the 
vignette; this would appear to be a programming error.

Quitting from lines 269-270 (maftools.Rmd)
Error: processing vignette 'maftools.Rmd' failed with diagnostics:
object 'Cytoband' not found
Execution halted
