I have put together a test class and methods
> setClass("foo",representation(x="numeric"))
[1] "foo"
> setMethod("plot","foo",function(x,y,...)boxplot(x,...))
[1] "plot"
> x <- rnorm(100)
> class(x) <- "foo"
> plot(x)
> y <- new("foo",x=rnorm(50))
> class(y)
[1] "foo"
My question is: should I have a "foo" function which sets the class
to "foo", please? or a sort of Validity checker, please?
Thanks,
Edna Bell
