Hi,I have invoked plot in a function (plot.func) as follows but when I check the built package, I get a warning: plot(x.pt,y.pt,xlim = c(0, 10), ylim = c(0,1), xlab= "xlab", ylab="ylab", main = "title", col = col,type = "l")? R CMD check my.package checking S3 generic/method consistency ... WARNING plot: ? function(x, ...) plot.func: ? function(x.pt, y.pt, arg3, arg4, "title", col, arg5) See section ?Generic functions and methods? in the ?Writing R Extensions? manual. Which plot argument is illegitimate or missing and how to eliminate the warning? Thanks Carol [[alternative HTML version deleted]]
Have you read the manual as requested? It will answer your question.

[R] warning on generic function when building R package
I would guess that x.pt does not have class "func", whatever that is.
You really ought to read the manual section indicated in the error.

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?

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.
