I have a question about the .C() function in R to call a C function. I
would like to know how to load the compiled code into R (if this is what
I need to do) . Iam not an expert in R neither in C. So the online help
was pretty much chinese for me.
I use R under linux, I use gcc to compile my code:
Let's take a very simple example:
double addition(double a,double b)
then under R I use
But obviously it does not work since I haven't loaded or compiled
anything under R
Error in .C("addition", as.double(a), as.double(b)) :
C/Fortran function name not in load table
I would really appreciate some help or some easy reading references.
Thank you very much,
