learning how to use function in the C library GSL (gnu scientific library),
to write C code, that I then plant to use in R. Is there any problem in
doing this? I mean, using functions of GSL to write C funtions to then use
them in R? I just want to make sure that this approach is correct, before I
invest more time trying to figure out how to include GSL functions into my
C functions. Any commentaries, insights or advice will be highly
appreciated.
per the posting guide ("Do Your Homework" section), you should do this:
RSiteSearch("GSL")
If you are considering doing something that might be submitted to
BioConductor, you should read up on what they require:
http://wiki.fhcrc.org/bioc/Package_Guidelines
IIRC, they tend to discourage the use of external libraries.
Maybe they do, but at least one package, GLAD, requires gsl in a
rather non-standard way and several others have really arcane
requirements for external libraries, some of which will not install on
any of my systems.
There are I believe 3 CRAN packages (gsl, BayesPanel, segclust) make
use of gsl.
The R API is rich with functions that provide a lot of what GSL has, so you
might want to study that before committing to GSL.
I agree: people who use gsl to do things R already does have caused
problems in the past.
If you want to distribute your package you should be aware that gsl is
not written with any concessions to portability. It is a real pain to
port to Windows (but I have managed with some versions and 32- and
64-bit builds as used for CRAN are at
