[R] warning on generic function when building R package

[carol white]

Thanks Murdoch.
defining
plot.func<- function(x=x.init, y=y.init, arg3, arg4, "title", col, arg5)
and if plot doesn't take the exact parameters of plot.func but modified of these parametersplot(x=x.pt,y=y.pt,xlim = c(0, 10), ylim = c(0,1), xlab= "xlab", ylab="ylab", main = "title", col = col,type = "l")  
then, how to define and invoke to be consisent?
Regards,

The first argument to plot.func needs to be called "x" if you want to
use it as a method.  Method signatures need to be consistent with the
generic signature.
