Thank you both, will then start from here.
I didn't know that Rcpp could be fed with the C code, that's good to know...!
Best wishes,

Dear R-devel,
I am trying to do something similar to dynamic length lists in R, but
at C level.
In R, that would be rather trivial:
- determine the length of the list
- create the list object
- store the values for each component
- access value components by using "[["
At C level, for a single c

Dear R-devel,
I'm trying to validate the results from a C function, against a (trial
and tested) older R function. For reasons unknown to me, the C
function seems to give different result sometimes at each trial, even
with the very same data.
These are the relevant outputs from R:

Dear R-devel,
I am now at a debugging phase, and would like to inspect the
(individual) values in an arbitrary R vector. It should be simple, but
after hours of reading I am simply unable to find the right
information.
A possible C code is:
±
# include
# include
# include
SEXP
Oh, that was straightforward enough...
Thanks very much, Simon.

Dear R devel,
Apologies for these (most probably trivial) questions, doing my first
attempt to call C from R (and actually learning C in the process).
I need to pass a matrix to C, and after reading R-exts.pdf (many
times), I was unable to find how to handle matrices at C-level...
