Dear Prof Ripley, thank you for your suggestions, they are as always very insightful! Although, anybody can miss a point or two as I just did in namespaces. Is the following correct?
Until redefined in the current namespace, plot.default (and all other plot.* methods) being defined in 'graphics' calls Axis.default also defined in 'graphics' and it is pointless to redefine Axis.default without redefining plot.default in the same namespace? It worked for me with Axis.numeric simply because the latter matches better than Axis.default and it is not defined in 'graphics'. So the question is: is there any obvious way around to redefine axis formatting to be used with all plot.* methods in the current namespace avoiding duplicating all the plot.* methods along with writing new Axis.* methods? Another understanding issue: it looks like I do really need to import all plot methods, copy and paste the code for them and export them again to make the whole idea work. I.e. it is not sufficient to simply importFrom(graphics, plot.default); define Axis.default; export(plot.default, Axis.default) in order to make it work. It is also not sufficient to have something like plot.default = graphics::plot.default in package code. In fact, to make it work I had to copy and paste the full implementation of plot.default (although without altering a single character). Am I missing something obvious? > Axis() is an S3 generic, not an S4 generic, so it does not > make sense to me to talk about 'signatures'.

Well, I would assume that default, POSIXct, POSIXlt and Date are kind of S3 signatures for Axis (Axis.*) But thanks for hinting at "methods", this was indeed what I needed.
