I try to create a complex accumulator. I would like to use an

accumulator for a box plot with the whisker data (

http://en.wikipedia.org/wiki/Box_plot ).

This short example

#include <boost/accumulators/accumulators.hpp>

#include <boost/accumulators/statistics/sum.hpp>

#include <boost/accumulators/statistics/min.hpp>

#include <boost/accumulators/statistics/max.hpp>

#include <boost/accumulators/statistics/mean.hpp>

#include <boost/accumulators/statistics/stats.hpp>

#include <boost/accumulators/statistics/count.hpp>

#include <boost/accumulators/statistics/median.hpp>

#include <boost/accumulators/statistics/variance.hpp>

#include <boost/accumulators/statistics/extended_p_square.hpp>

whoops, should be:

#include <boost/accumulators/statistics/extended_p_square_quantile.hpp>

#include <boost/array.hpp>

using namespace boost::accumulators;

typedef accumulator_set<double, stats<

tag::count,

tag::sum,

tag::mean,

tag::extended_p_square_quantile //*

accumulator_t;

int main()

{

boost::array<double,3> probs = {0.25, 0.50, 0.75};

accumulator_t acc(extended_p_square_probabilities = probs);

}

compiles only, if I comment the //* line, but with the quantil tag the

compiler creates this errors:

<snip>

The errors went away for me when I included the correct header. You

might check the docs for the statistics you're using. The docs aren't

great, but they at least tell you what headers to include.

http://www.boost.org/doc/libs/1_53_0/doc/html/accumulators/user_s_guide.html#accumulators.user_s_guide.the_statistical_accumulators_library.extended_p_square_quantile

I can solve the problem :-P

I have include these headers:

        #include <boost/array.hpp>

        #include <boost/accumulators/statistics.hpp>

        #include <boost/accumulators/accumulators.hpp>

But my variable m_times is a std::map<std::string, accumulator> and I can not push the accumulator with m_times[<some string>] = Accumulator(...)

I need the insert method of the map with a std::pair and for accessing the element does not work the m_times[<some string>](<a value>), I need

the iterator of the map element and push the value to the accumulator with it->second(<a value>)
