Thank you very much for your reply. You confirm what I suppose.
Can you give me a reference of that you wrote? I need it for a report.
Thanks again.
PS: sorry Uwe for the previous reply, not to the list.
... where I replied it is in the manual "R Labguage Definition".

Hello everybody.
My issue arise when I build a package with my functions. This package is
for
personal purposes only and it will not submitted to CRAN.
Anyway, this may be an opportunity for myself to clear the S3 methods
concept. I read the R manual and some books about R programming but they
are
usually S4 oriented.
I call a function plot.days(). When I check the package I obtain some
inconsistencies because this function is a method of the plot() function
and
it requires at least the same arguments.
Since an object call days doesn't exist, I am not interested to access my
function using plot() but I would like to name it plot.days().
Is there anyway to declare that my plot.days() function is not a method
for
the plot() function?
I hope the question is clear, despite methods are a new world for me.
The S3 method definition happens only by the name of the method:
"NameOfTheGeneric.Class". Hence plot.days is by definition a method for the
"plot" generic for objects of class "days". If you want a function that is
not such a method, rename it. plot_days will do, for example.

Thank you very much.
