[Bioc-devel] Namespace and function 'open'

[Markus Schmidberger]

The function "open" is located in the "base" package. This should be 
imported automatically.

importFrom(base, open)
Fails with an error:

Error in asNamespace(ns, base.OK = FALSE) :
  operation not allowed on base name space

Best,
Markus
