Hello,
Are there any good tools available for monitoring the performance of R? I'm
wanting to capture things such as time elapsed in evaluating an expression,
memory usage over time (or operation), and so on.
I could build my own but would like to follow established practice, if there
is one.

I'm aware that this post does not really comply with the posting guide with

On the subject of clarification, Reference Classes are not really an
"addition" to S4. They are a programming interface to allow OOP (i.e.,
C++ or Java-style) programming in R.
They do use some S4 tools but rely more on some valuable existing
techniques for dealing with environments, such as

I've just tried to compile R 2.12.0 from source as I think I found an error

It might have to do something with spaces and the interpretation of

Thanks a lot for the comments! I'll give the serveral alternatives a try to
see if it gets me what I want.

Hello Everyone!
I am trying to extend the class "call", but keep getting errors whatever I do:
setClass("mycall", contains = "call")
#[1] "mycall"
new("mycall")

Just a clarification for posterity - R5 has nothing to do with the new
reference classes. It's not even an official name, but informally it's a
collection of ideas for an entirely new object system that can replace both S3
and S4 (not that it will but it should be seen as having the capability t
