[Bioc-sig-seq] graph package conflict with rtracklayer

[Cook, Malcolm]

Michael & Robert,

If I load the graph package prior to rtracklayer, import.bed generates an error and fails.  It otherwise succeeds if I don't load the graph package.

It happens both with rtracklayer from svn and production.

Look:

In a fresh session:

> library(graph)
> library(rtracklayer)
Loading required package: RCurl
Loading required package: bitops
> b <- import.bed('my.bed')
Error in function (classes, fdef, mtable)  : 
  unable to find an inherited method for function "import.ucsc", for signature "file"
