Dear all, I am trying to define "+" method for my newly defined s4 class
which is as follows:
setClass("Me", sealed=F,representation(x1 = "numeric", x2 = "character"))
new1 <- new("Me", x1=2, x2="comment1")
new2 <- new("Me", x1=3, x2="comment1")
setMethod("+", "Me", definition=function(x,y) cat(x@x1 + y@x1, "\n"))
However while am trying to set method, it fails:
Error in conformMethod(signature, mnames, fnames, f, fdef, definition) :
in method for '+' with signature 'e1="Me"': formal arguments (e1 = "Me",
e2 = "Me") omitted in the method definition cannot be in the signature
I am just started learning s4 class system therefore please forgive me if I
have some any bad mistakes. Anyway I would really appreciate if someone
point me how should I proceed.
Thanks and reagrds,
