...do not understand much C, however, I'll give it a try). I am trying to include C++ code into an R routine, where the C++ code looks: #include <iostream> using namespace std; void foo (double* x, double* y, double* out) { out[0] = x[0] + y[0]; } Back in R, the command R CMD SHLIB --preclean -o xplusy works fine resulting in two new files, xplusy.o and xplusy.so. The wrapper in R is: dyn.load("xplusy.so") xplusy <- function(x, y){ .C("foo", as.double(x), as.double(y), out=double(1))$out } xplusy(1, 2) dyn.unload("xplusy.so") Now, dyn.load() works...

I need to have all elements of a matrix multiplied by a weight before being post-multiplied by itself, as shown in the forst block of codes below. I can also multiply the matrix by the square root of the weight and then take the outer product. Actually, what I need is this. Denote each row of the matrix by a row vector as xi and each element of the weighting vector as wi. Then, I need the

Hi This is a question prompted by the mac version of R, but as I see it, it should have broader interest. These days the CRAN Mac binary per default compiles every package for two architectures. First i386 and then ppc. In between the two compilation runs, any object files in pkgname/src is removed. This cleanup is necessary since otherwise Make would not recompile the object files
