Hello, when working with the rpy2 bioconductor extensions I noticed that one of the wrapped classes in bioc.annotationdbi was giving rather strange RRuntimeErrors, so I decided to dive in.
The offending code was
_subset = getmethod("subset", signature = StrVector(["AnnDbBimap", ]),
where="package:AnnotationDbi")
when invoked directly (i.e. _subset() without the class wrapping) and without
any default argument, instead of expecting an error for nonspecified
arguments, I get
Error in as.vector(x, "character") : cannot coerce type 'closure' to vector of
type 'character'
However this is a call without arguments, so something unexpected.
Surprisingly, a similar call to the superclass ("Bimap") does not seem to have
this problem.
How to debug further? Or am I doing something wrong?
For reference, I run Python 2.7 w/rpy2 2.2 (the latest available verison),
self compiled, and R 2.14.
