dput() is intended to be parsed by R so the above is not possible without
massaging the output. But why in the would would you use dput() for
something that you want to read in Java? Why don't you use a format that
Java can read easily - such as JSON?
Cheers,

Yeap, except i was

I am reading into Java dput output for a matrix, more specifically for a
file backed big-matrix. I basically need to lift dimnames for a matrix from
dput output. It's no big deal, but the code is very 'hackish' due to the
need to get rid of quotes, endlines, parenthesis, etc. I was wondering if i
I work with problems that have rather large data requirements -- typically
a bunch of multigig arrays. Given how generous R is with using memory, the
only way for me to work with R has been to use bigmatrices from bigmemory
package. One thing that is missing a bit is interoperability of
bigmemory matrices are simply arrays of native types (typically doubles,
but bm supports other types, too) so they are trivially readable/writable
from both C++ (just read into memory and cast to the array type) and Java
(e.g, DoubleBuffer view on a ByteBuffer). So the question is what

I'd like to have a version of a package that doesn't include sources. I
thought that this could be achieved by using binary option in R CMD build,
but in fact it packages source code that could be easily printed once the
library is loaded. Is there an option to avoid visibility of the source?
OK, gentlemen, i agree with you in general. I was not talking about a general
purpose, general use package that one prepares for CRAN. I am sure you are
familiar professionally or can imagine situations where you need to
demonstrate a solution to a specific task without fully disclosing the

Thank you very much, gentlemen. It seems reference classes will make my life
much easier. I won't pretend that i fully understand the wizardry with
environments that you do, but it works :). Namely the steps to mtrace a
class method by doing what John and Mark outlined

How do you debug methods of a reference class? I've been using mtrace, which
is excellent, but i cannot figure out how to mtrace a reference class
method. Maybe there is some other way to debug these, for example with
ordinary trace? for now i am only able to use options(error=recover), which

This looks awesome -- it is precisely what i wanted. I have started hacking
with passing around environments to simulate behavior of classes i was
after, but this is so much neater. Reference classes seem to do precisely
what i wanted. Thank you very much.

Dirk, thanks for your reply. I posted my answer right away and went on
vacation. My post was pending since then. Still cannot post, so I opened
another profile -- maybe this time it gets through.
To answer your questions, I run R-2.12.1 on 64 bit RedHat Linux on Xeon

Hi all. I started looking at Rcpp, which looks pretty great, actually. At the
moment just trying to compile a module to get a feel how it all works without
fully understanding how all the pieces fit together.
Basically, i took the first example from Rcpp modules vignette:
fun.cpp
Hi all, i am trying to compile a test, calling from C code R Lapack shared
libraries. In particular, i am calling simple LAPACK driver
