Learn R Programming

MixedPsy

The aim of the MixedPsy project is to provide statistical tools (such as R codes, models and tutorials) for the psychophysics community. This project has a special focus on open-source programming language. For the moment, the codes and documentation are restricted to R, tough other open programming languages (such as Julia) might be considered in the future.

19 April 2010 Work In Progress. See https://mixedpsychophysics.wordpress.com/ for a stable release and documentation.
