Hi Florian,
You could try the Rcpp package for the interface. It works pretty well for
me.

The problem in this example is (plausibly) that the argument evaluation
code in method selection itself uses an internal C-level version of
try(), overriding the user's setting.
If this is the bug, I'll have to defer to more expert advice on whether,
and if so how, the code can adjust for the

Actually, the above is true but assumes that you're running R's REPL and not
your own R_ReadConsole (it will work even in your ReadConsole but unix handlers

Use

The code below is very fragile and unix-specific.

in RKWard we run the following periodically during idle phases:

There does indeed seem to be a bug in the C code that implements
callNextMethod, with the effect of adding a spurious index to calls to
the primitive `[` code with more than 2 subscripts.
The message "incorrect number of dimensions" is telling the truth, the
primitive code gets 4 subscripts in

Dear list,
I am trying to embed R into a C++ program. After some tinkering,
reading the documentation and browsing the source code I have this
more or less working. A very very condensed and very simplified
version of the code is included below.
The program can create plots. However, after the pl

largely undocumented tcltk package, but I've finally hit a wall. I can't
even think of any sufficiently specific search terms to use for this.

I believe this is a misdiagnosis: the 'rounding' is done by
as.character (as the help for argument 'levels' in ?factor does say)
and ?as.character has a full explanation (and is linked from the
relevant part of ?factor).
as.numeric(as.character()) should do the trick.

Please don't pick things out of context. It does not say .C() is
deprecated and it is not talking about R code: it says
There are default variables and rules for this (determined when R is

Hi,
I am writing a R package and having a bit of trouble to have the C++
code working.
I was planing using the .C interface function, however I found the

R 2.12.0.) in the R-exts manual.
So this interface function should not b

AFAIK, you simply need to put the path to the correct pg_config first
in your path -- depending how the PostgreSQL installation was done you
may also need to ensure that its libraries are in your
