It was used in my c++ code :) that's why I had problems héhé. R.

I agree with everybody too :) I still like my example, and I obviously respect operator- "in general". What I can't square is whether the code for operator- (which I may in fact have defined the way I like it) _actually gets called_. In what I sent on March 31 as the NewYear/Easter example: R> NewYear <- as.Date("2013-01-01") R> Easter <- Sys.Date() R> cppFunction('double ddiff(Date a, Date b) { return a - b; }') R> cppFunction('double ddiff2(Date a, Date b) { return b - a; }') R> ddiff(NewYear, Easter) [1] 89 ## I find this more logical R> ddiff2(NewYear, Easter) [1] -89 ## closer to R's difftime and 'odd' to me R> If it isn't used here, where is it actually used?
