I would not want my standard graphics output to be changed just because
some package ("prettyB") gets loaded, which could happen
*unintentionally* as a dependency (or a dependency of a dependency, ...)
of another package.
What about some kind of prettyB::enable_prettyB() function which does
registerS3method("plot", "default", prettyB::plot.default,
asNamespace("graphics"))
similar to delayed method registration (see, e.g.,
https://github.com/r-lib/vctrs/blob/master/R/register-s3.R), so that a
user needs to switch to "prettyB" graphics explicitly ?
Or more simply: call the method prettyBplot.

Resetting to graphics::plot.default should be made possible as well.
The question remains whether registerS3method() can be used at all,
since the help says:
Internal namespace support functions. Not intended to be called
directly, and only visible because of the special nature of the
‘base’ namespace.
Cheers,
Sebastian

Dear All,
I'm developing a small package to make plotting methods a little bit
nicer looking:
https://github.com/jumpingrivers/prettyB/
The general idea is to replace plot.default() with an alternative
(matching all arguments) and export. This would allow users to simply
load the package and use base graphics functions as normal, but get a
pretty graph.
The general pattern I follow is:
https://github.com/jumpingrivers/prettyB/blob/master/R/plot.R#L23
which then includes S3method(plot,default) in my NAMESPACE file. When
building and checking the package I get
Registered S3 methods from standard package(s) overwritten by 'prettyB':
method from
plot.default graphics
which CRAN does not permit.
Question: Is it possible to achieve the functionality I'm after
(replacing the default plot.default() functions) while following the
CRAN rules?
Thanks
Colin
