I'm interfacing to C code that uses 1-based indexing on arrays -- it ignores the zeroth element. Thus, input vectors from R must be moved up one, and output arrays must be moved down one.
What is the best way to deal with this using R internal code? My current approach is: For an input R vector of length n, allocate a new vector(v) of length n+1 and copy input into v[1] to v[1+n]. Call with new vector. For an output array(a) of length n, allocate a new vector of length n-1 and copy a[1] to a[n] into v[0] to v[n-1]. If this is the best approach, is there an idiom for copying vectors? -Lopaka ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
