Dear R enthusiasts, I am happy to announce that the package Leab*R*a is now on CRAN (https://cran.r-project.org/web/packages/leabRa/) Leab*R*a provides the Leabra artificial neural network algorithm (O?Reilly, 1996, ftp://grey.colorado.edu/pub/oreilly/thesis/oreilly_thesis.all.pdf) for R. Leabra stands for ?local error driven and associative biologically realistic algorithm?. It is the Rolls Royce of artificial neural networks because it combines error driven learning and self organized learning in an elegant way, while focusing on a biologically plausible learning rule. The vignette shows how to construct networks: https://cran.r-project.org/web/packages/leabRa/vignettes/leabRa.html Feedback welcome: https://github.com/johannes-titz/leabRa/ Best, Johannes
