[Rd] .S4methods inconsistent behavior with methods, .S3methods

2016-11-03 Thread Richard Cotton 
If I call

.S4methods(sd)

I get the error

## Error in getGeneric(generic.function) :
##   argument 'f' must be a string, generic function, or primitive:
got an ordinary function

By contrast, methods and .S3methods just state that no methods are found.

methods(sd)
## no methods found
S3methods(sd)
## no methods found

It seems like the behavior of these functions ought to be consistent.

Maybe they should split the difference and say no methods are found,
but warn the the input is not generic?

I agree that this would be a useful option sometimes.

So I would be supportive to get such an option, say,

   R CMD check --no-stop-on-error  

into R if someone provided (relatively small) patches to the R
sources (i.e. subversion repos at https://svn.r-project.org/R/trunk/ ).
The relevant source code should basically all be in
src/library/tools/R/testing.R

Note that this may be complicated, also because "parallel"
checking is available in parts, via the TEST_MC_CORES
environment variable ((which is currently only quickly
documented in the 'R Administration ..' manual))

   R CMD check --no-stop-on-error  


A couple of years ago the behavior of 'R CMD check' was changed to
continue checking (e.g. the examples) after many types of errors, and
to output a summary count of errors at the end if any have occurred.
So --no-stop-on-error could easily be interpreted as an option that
controls this behavior (and would also suggest that the default has
been reverted back to what it was prior to R 3.2.0), rather than an
option that specifically controls what should happen while running
the tests.

Cheers,
H.
