[R] Load the shared object/DLL

Dear All, I have written a function in c (in a file named 'a.c') as follows, void convolve(double *a, int *na, double *b, int *nb, double *ab) { int i, j, nab = *na + *nb - 1; for(i = 0; i < nab; i++) ab[i] = 0.0; for(i = 0; i < *na; i++) for(j = 0; j < *nb; j++) ab[i + j] += a

[R] How to convert the "user coordinate system" in R graph to "normal coordinate system" whose origin is the upper-left cornner of the drawing area?

Dear friends, The user coordiante system in the R graphics is easy to understand as it simply corresponds to the range of values on the axes of the plot. However, sometimes, we want to kown the coordinates of a region in other system, e.g., the normal coordinate system whose origin is the th
