...ction and compile it.
However in R I can't see the function I have defined in C++.
I have read some web-pages about Rcpp and C++ but it is a bit confusion
for me.
Anyway,
This is the C++-code:
#include <Rcpp.h>
using namespace Rcpp;
// [[Rcpp::export]]
List compute_values_cpp(int totalPoints = 1e5, double angle_increment =
0.01, int radius = 400, double grow = 3.64) {
double xn = 0.5;
double angle = 0.1;
double xn_plus_one, yn_plus_one;
NumericVector x(totalPoints);
NumericVector y(totalPoints);
for (int i=0; i<totalPoints; i++) {
xn_plus_one = xn*cos(angle)*radius...

Calculating row COUNTs
hi everyone,
I''m trying to do a simple calculation in my rails project. I would like
to find all rows in a table that match the given id of another table
(ie. comment_id) and has the value = 1 ("value" is a field in the
table), then add those values up. Next find the same rows with the
value = -1 and add those values up also. Finally, I would like to find
the total.

_One call_ of sourceCpp() compiles AND links AND loads AND runs the example R

For reference, the current mmsp.cpp follows.

encoder observation
Hello!
First of all a question:
When you make the encoder tables (ie: mode_e.h)
do you use the mapping0_forward function?
Because you made the encoder tables, and after this
you did a minor correction in the final beta4 ...
(this correction was:
additional[0]=fabs(additional[0]*scale);
in the mapping0_forward function)
(I see this was a bug, and the modification
was correct, but this correction
