Metaflow is one of my favourite R packages. Actually, it’s a Python module, but the R package provides a set of bindings for running R code through Metaflow. Recently I’ve spent a good amount of effort trying to improve the way that R data is translated to the Python side of Metaflow, but I just can’t get it to work. So I thought I’d post about what I’ve learnt. Maybe someone will have an answer.
