The objects and parameters in R package appear to have increasingly both the "." and the "_" version of names.
For example, in R 3.2.0 the package
stats has both
format.perc. The current conversion rule for high-level utilities such as
importr is to convert "." (invalid character for Python symbols) into "" but this is obviously breaking when the "" version is also defined in the R package (fortunately
rpy2 is checking rather than silently override).
What could be a good default conversion rule that would keep the automatic conversion work (without the need to specify the conversion manually for such cases) ?
