# 8 Code maintenance, credits, contact, etc.

## 8.1 Code maintenance

Distribution of Genepop as an R package means that the code is portable to the major operating systems supported by R. New version are checked using a variety of tools available in the R environment (including valgrind and so-called sanitizers). Tests against more or less standard examples from the literature are also applied. These tests can be found in the `tests/testthat` directory of the distributed archive.

## 8.2 Credits for the current version

The R package and the R markdown version of the documentation were originally developed by Jimmy Lopez (Labex Cemeb) and Khalid Belkhir (Institut des Sciences de l’Évolution) from the C++ sources and LaTeX documentation of the Genepop executable version 4.6, and further modified by F. Rousset.

## 8.3 Previous history

Version 4.0 of Genepop was a C++ rewrite of Genepop 3.4 (Raymond and Rousset 1995b) by F.R., using draft C translations of many Genepop modules by O. Guillaume, N. Benhamou and A. André, and some draft C++ classes by R. Leblois.

Beyond M. Raymond and F.R., credit for previous Genepop code is as follows. The complete enumeration procedure for HW tests was derived from Fortran code provided by E. J. Louis (Inst. Mol. Med., Oxford, UK). Some of the procedures for isolation by distance “between individuals” were first written by R. Leblois with help from S. Piry (INRA-CBGP, Montpellier). P. David, É. Imbert and S. Samadi wrote some early code in 1993.

## 8.4 Contact

If you think you have found a bug, you can contact me. Requests which do not meet the following requirements are likely to meet poor response. Please provide a minimal input file illustrating the suspected problem, whenever relevant. Please use the latest version of Genepop taken from a web page I maintain. Note that I do not maintain the “Genepop on the web” port of Genepop: any question related to this port should be addressed to Eleanor Morgan. Please specify the version of Genepop you are using. Please do not ask whether Genepop is commercial software. Please read this documentation.

I may answer queries about methods implemented in Genepop, and the more so when they are specific to Genepop. But in most cases there are published references describing the methods, cited in this documentation. Please read this documentation.

### 8.4.1 Bug fixes since release of Genepop version 3.4 in May 2003 until first release of Genepop 4.0:

The sign of the lower confidence interval bound for regression slope in Isolde did not appear on output file when it was negative.

For computation of allele size-based statistics (Option 6.2 and 6.4) with the option “allele name = allele size”, the allele ‘99’ was interpreted as having size zero.

See the distribution page for more recent bug fixes.
