Created by Alexis Roche and last modified

This experimental branch tests the feasibility of binding with numpy some libraries written in C for R or S-PLUS, such as the LME4 package (linear and nonlinear mixed models) by Douglas M. Bates. Our goal is typically to make it fast to run routines in a massively univariate fashion, by looping over voxels in C (via cython) rather than in R. This module needs R to be installed on the system to run as it will link dynamically with libR. This branch is distributed in GPL license due to the dependence on R, thus it is intended to stay aside from the Nipy mainline and be used as an optional plug-in.
