The Special Programme for Research and Training in Tropical Diseases (TDR) sponsored by UNICEF/UNDP/World Bank/WHO has supported the preparation of an R add-on package, Epicalc, to enable R (an open-source statistical software) to more easily deal with epidemiological data. Epicalc, written by Virasakdi Chongsuvivatwong of Prince of Songkla University, Hat Yai, Thailand, has been well accepted by members of the R core-team and the package is downloadable from CRAN (Comprehensive R Archive Network) which is mirrored by 69 academic institutes in 29 countries. Equally, Epicalc has been welcomed by students and users alike. On one hand, it assists data analysts in data exploration and management. On the other hand, it helps young epidemiologists to learn the key terms and concepts based on numerical and graphical results of the analysis.
