[R] Problem with C extension

[Markus Schmidberger]

Hello,

I try to write an extension in C, to get a faster functions.
Therefore I have to add an element (vector) to a vector. The command in 
R is very simple: x = c(x,a)
But in C I have the problem to reallocate my vector for getting more 
space. Everything I tried, I get a "Segmentation fault".

So, how can I combine two vectors in C and give the result back to R 
(return(x))?

Thanks
Markus Schmidberger
