Yes, I had looked at R.oo, S4 and proto before beginning coding. I had
initially assumed that S4 was an enhancement of or replacement to R.oo that was
implemented at a lower level and had decided to go with the 'future' of OO in R.
These assumptions were not necessarily correct.

I am considering a package with a namespace (Rgraphviz from Bioc). I
essentially want to have some error handling for loading the dll,
something like wrapping it into tryCatch or similar (reason: see
below). Right now I am loading the dynamic libraries by useDynLib in
my NAMESPACE file. Whe
In 2.8.1/Windows:
According to ? :
Details:
For numeric arguments 'from:to' is equivalent to 'seq(from, to)' ...
Value:
For numeric arguments, a numeric vector. This will be of type
'integer' if 'from' and 'to' are both integers and representable
in the integer typ
sys.function might be useful.

ah good, if you're frustrated with Java you'll find R very different ;)

If I'm reading help files correctly, it is not possible to overload
'(' (which would be the most elegant solution, I suppose). I can
enclose the slotted data
Dear Liviu,
That's very helpful, thank you!

Not a direct answer to your question, but...
You might consider using the R.oo package, from H. Bengtsson. It's
very stable, written in pure R, and cleanly allows you to do
pass-by-reference OO programming, with no tricks.
