[Rd] "Use of ‘.C’ for C++ is now deprecated and will be removed in R 2.12.0"

[Florian Breitwieser]

Hi,

I am writing a R package and having a bit of trouble to have the C++
code working.

I was planing using the .C interface function, however I found the
comment (Use of ‘.C’ for C++ is now deprecated and will be removed in
R 2.12.0.) in the R-exts manual.

So this interface function should not be used anymore - .Call() or
Rcpp instead? What is the reason for the deprecation?

Thanks,
Florian
