[Rd] CRAN package with dependencies on Bioconductor

[Prof Brian Ripley]

Note that until May 8 graph was a CRAN packge and the current version 
was 1.30.0.  So of course CRAN binary packages built between April 26 
and May 8 were built against the current CRAN version of graph, for 
any version of R.
