This is a simple R.oo question but I, thankfully, hope that someone would explain it to me so I would better understand this work frame. I create this class:

setConstructorS3("MyExample", function(param=0) {   print(paste("called with param=", param))   extend(Object(), "MyExample",
    .param = param

>From what is printed out, who made the second call to the class with
the default param?

> MyExample(1)

[1] "called with param= 1"
[1] "called with param= 0"                # <- this is line in question
[1] "MyExample: 0x02831708"
