Subject: Re: [R] R and C++ compared with only C++
As always, it depends on your priorities and motivation. If
that extra 10% is important and if you can be bothered
writing the C++, then putting the whole thing into C++ may be
worth it. If not then you could let R deal with the input
My computer is a pentium 4 running at 2.4 GHz.
My R is 1.7.1
I have written a program in R that calls C++. The program spends most of the
time in C++ ( 90% ). R basically deals with output and input.
How slower can this be compared with the program I would get from rewriting
everything in C++?
