Re: [R] matrix to a C function

Christophe, That's another question for the R-devel mailing list. A few things however. Short answer : no it is not possible. I don't think x[i,j] is even syntactically valid in C or C++. I'd suggest you to give a go at the .Call interface that lets you manipulate R objects directly. So in

[R] matrix to a C function
