R is a language dedicated to statistics. Python is a general purpose language with statistics module. R has more statistical analysis features than Python, and specialized syntaxes. However, when it comes to building complex analysis pipelines that mix statistics with e.g. image analysis, as in the case of brain imaging, the richness of Python is an invaluable asset.
