I am developing a S4 class but have had trouble to make setMethod work in Window 7. I tested an example found in the setMethod manual:
> require(graphics) > setMethod("plot", signature(x="track", y="missing"), + function(x, y, ...) plot(slot(x, "x"), slot(x, "y"), ...) + ) It gave me: Error in setMethod("plot", signature(x = "track", y = "missing"), function(x, : unused argument(s) (function(x, y, ...) plot(slot(x, "x"), slot(x, "y"), ...)) It works perfectly fine in Linux. Does anybody know why? Thanks in advance!
