Non-Parametric Concordance Coefficient

A non-parametric test for multi-observer concordance and differences between concordances in (un)balanced data.


NEWS file for the nopaco package

Version 1.0.3

  • Added a vignette explaining the basic use of the package. The vignette works out an expample which data is given in the newly added data scores.rda (also requiring newly added data documentation)
  • A major change was made by replacing the Google dense-hash (and corresponding configuration script) by an c++11 std unordered_map in order to solve the poor portability of the package.
  • According to rcheck tool by Thomas Kalibera (see the samplePsi.cpp file did contain some unprotected variables which are now protected.
  • Concordance.test could sometimes give p values slightly larger (in the order of machine precision) than 1. This is resolved.
  • Implementation of tied values is handled in this version.
  • The .samplePsi function did not correctly release the random.seed within the global.env causing random number generators to be non random anymore.
  • Fixed a warning (Found no call to: ‘R_useDynamicSymbols’) by adding a call to R_useDynamicSymbols(info, TRUE); in register.cpp

Version 0.99.8

  • The previous version still did not compile on solaris (and possible also OSX). I found the cause in the configuration file which was not enforcing c++11. This is fixed in this version.

Version 0.99.7

  • The previous version contained memory leaks. These have been corrected by: replacing a delete by free (in getPsi.cpp:68) freeing pointers pStateLimits and pState (in exactdistribution202.cpp:296-297) No more leaks are found by the valgrind tool.
  • After submission to CRAN, Kurt Hornik reported a failure to install on Debian Linux. Although the error could not be reproduced, it is assumed to be related to the c++11 dependency. The current version includes 'CXX_STD = CXX11' in the Makevars file in order to force compilation and linking with a C++11 compiler.
    • The previous nopaco package did not compile on some systems because of non supported c++ headers. These headers were used in the external code (sparsehash @google). The current version includes a configure script that came with the sparsehash code hopefully solving the issue.
    • remove some non-used files shipped with the external sparsehash code.
    • in addition to the 'cph' role for google, I added 'aut' in the description file.
    • more specifically identified the files to which the copyright applies

Version 0.99.4 First version submitted to CRAN
