Is there an R-language interface to the R API C-language functions
Rf_logspace_add()
and Rf_logspace_sub()? I don't see one but I may not looking under the
right name.
Various packages have functions which do that same sort
of thing (log(exp(x)+exp(y)) and log(exp(x)-exp(y)) without unnecessary
Thank you very much! Just what I needed.
Too bad I never got to understand what was wrong with my original code...
Thanks again!

Over the years, this has been useful to me (not just in R) for many
nonlinear optimization tasks. The alternatives often clutter the screen.

For that type of code, it is actually quite simpler to learn c++ than it

Romain,
Thanks for your quick response. I've already received that suggestion,
but, besides of haven't ever used C++, I wanted to understand first
what am I doing wrong. Still, would you give me a small example, in R
C++, of:
- Creating a generic vector "L1" of size N
- Creating a data.frame
Hello,
Any particular reason you're not using Rcpp? You would have access to
nice abstraction instead of these MACROS all over the place.
The cost of these abstractions is close to 0.
Looping around and SET_LENGTH is going to be quite expensive. I would
urge you to accumulate data in data st
Hi!
I didn't wanted to do this but I think that this is the easiest way
for you to understand my problem (thanks again for all the comments
that you have made). Here is a copy of the function that I'm working
