[accumulator] compiler error with quantil
Hello, 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 ). My typedef shows at the momen like this: typedef boost::accumulators::accumulator_set<double, boost::accumulators::stats< boost::accumulators::tag::count, boost::accumulators::tag::sum, //boost::accumulators::tag::median, boost::accumulators::tag::mean, boost::accumulators::tag::variance, boost::accumulators::tag::min, boost::accumulators::tag::max, boost::accumulators::tag::extended_p_square
Accumulator;
I would like to create the 25% & 75% quantil and replace the median with the 50% quantil, so I have defined the ctor accumulator call like this: boost::array<double, 3> probs = {0.25, 0.5, 0.75}; m_times[p_name] = Accumulator( boost::accumulators::extended_p_square_probabilities = probs ); (the median is disabled and m_times is a std::map<std::string, Accumulator>). At this point I get a compiler errors: /Developer/opt/Boost/1.53.0/include/boost/accumulators/statistics/extended_p_square.hpp: In constructor 'boost::accumulators::impl::extended_p_square_impl<Sample>::extended_p_square_impl(const Args&) [with Args = boost::parameter::aux::arg_list<boost::parameter::aux::tagged_argument<boost::accumulators::tag::accumulator, boost::accumulators::accumulator_set<double, boost::accumulators::stats<boost::accumulators::tag::count, boost::accumulators::tag::sum, boost::accumulators::tag::mean, boost::accumulators::tag::variance, boost::accumulators::tag::min, boost::accumulators::tag::max, boost::accumulators::tag::extended_p_square, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na>, void> >, boost::parameter::aux::empty_arg_list>, Sample = double]': /Developer/opt/Boost/1.53.0/include/boost/accumulators/framework/depends_on.hpp:319: instantiated from 'boost::accumulators::detail::accumulator_wrapper<Accumulator, Feature>::accumulator_wrapper(const Args&) [with Args = boost::parameter::aux::arg_list<boost::parameter::aux::tagged_argument<boost::accumulators::tag::accumulator, boost::accumulators::accumulator_set<double, boost::accumulators::stats<boost::accumulators::tag::count, boost::accumulators::tag::sum, boost::accumulators::tag::mean, boost::accumulators::tag::variance, boost::accumulators::tag::min, boost::accumulators::tag::max, boost::accumulators::tag::extended_p_square, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na>, void> >, boost::parameter::aux::empty_arg_list>, Accumulator = boost::accumulators::impl::extended_p_square_impl<double>, Feature = boost::accumulators::tag::extended_p_square]' .... I need one accumulator for all the data. I'm using Boost 1.53. How can I create working code? Thanks for help Phil

whoops, should be: #include <boost/accumulators/statistics/extended_p_square_quantile.hpp>
<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... -- Eric Niebler Boost.org http://www.boost.org

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>) Phil
