R S4 setreplace方法中存在错误

我试图在重载方法的定义中定义S4中的[参数名称必须与原始方法的名称完全匹配

setReplaceMethod(f="[", signature="A", function(x, i, j, ..., value){return(x)})

注意

x

（您使用了

对象

。

请参见

getGeneric（“[
setClass(Class = "A",
     representation = representation(x = "numeric"),
     prototype = prototype(x = 0))

setReplaceMethod(f = "[",
             signature = signature("A", "integer", "integer", "numeric"),
             definition = function(object, i, j, value) {
                 return(object)
             })

Error in conformMethod(signature, mnames, fnames, f, fdef, definition) : 
  in method for '[<-' with signature 'x="A"': formal arguments (x = "A", i = "A", j = "A", value = "A") 
omitted in the method definition cannot be in the signature

setReplaceMethod(f="[", signature="A", function(x, i, j, ..., value){return(x)})
