Thanks Martin and Hadley, this is very helpful.
I should also add that I'm constantly reading the source code, but sometimes
a response like this one can eliminate many, many hours of puzzlement. Much
appreciated.

The best advice
Very helpful, thank you.
A couple other questions, please:
1. I've got a function written in C, named "my_c_function". In my R code I

result <- .Call("my_c_function", int_vector, str_vector)
The prototype of "my_c_func

Hello,
I've created this class:
setClass("example",
representation (
size = "numeric",
id= "character"
)
)
