Hello, ?as.character says that the as.character function is a generic with usage: as.character(x, ...). So, I want to create an S4 object with an as.character method following the above usage, but I get the below error telling me that ... isn't in the generic for as.character.
> setClass("tmp", "numeric") > setMethod("as.character", "tmp", function(x, ...) paste(x, c(...))) Error in rematchDefinition(definition, fdef, mnames, fnames, signature) : Methods can add arguments to the generic only if "..." is an argument to the generic Am I reading the documentation incorrectly? How do I correctly pass the ... object to the method for this "tmp" object? However I note that looking at the generic function, I see no mention of ... (despite the documentation). > getGeneric("as.character") standardGeneric for "as.character" defined from package "base" function (x) standardGeneric("as.character", .Primitive("as.character")) <environment: 0145EDC4> Methods may be defined for arguments: x So, briefly, is the documentation wrong? Am I doing something wrong? Can I create an as.character method and pass additional arguments to it as I think I should be able to?
