Thanks to everyone who replied to my query. It is much appreciated. Reading
Hadley Wickham's book Advanced R and in particular S3 classes reveals that a
class needs to be written allowing inhertinance (by passing the subclass
parameter as an argument) and its methods written carefully to functio
You might find http://adv-r.hadley.nz/s3.html to be helpful (in
particular, http://adv-r.hadley.nz/s3.html#constructors-1, gives my
advice about subclass constructors)

x <- x + 1
f1( x, ... )
}
f2( 2, y=3 )

The S3 class model isn't really a class model. It's more a way of
overloading functions. So it's rather simple, and there's less there
than you might be expecting. I always thought the "Object Oriented
Programming" chapter of the R language definition manual that ships
with R was a very good treatm
Hi R Users,
I am relatively new to programming in R … so I apologise if my questions appear
‘dumb’.
I am using a package that defines a number of S3 classes. I want to create an
S3 child class of one of these classes. The parent class has a contractor with
many arguments. I have been having di
