[Rd] Re: [R] Changing graphics defaults [was: changing (core) function argument defaults?]

[Spencer Graves]

      Under the S3 standard, you could make a local copy of any function 
and change the defaults in that local copy.  That may not always work 
under the S4 standard methods dispatch going to code hidden in 
namespaces.  In any event, it should be easy (and safer) to write a 
function with a slightly different name, e.g., adding a dot "." to the 
end of the name, that would have different defaults and would do nothing 
but call the function of interest.  This might be safer

      I don't have any suggestions about changing graphics defaults 
other than to ask for that specifically -- e.g., by changing the subject 
line to this email. 

      hope this helps.  spencer graves
