DataFrameMacros.jl is a Julia package that makes it easier to manipulate DataFrames, by rewriting code into source-function-sink expressions that conform to DataFrames.jl’s more verbose mini-language. In version v0.2 (and v0.2.1) I have added a couple new features that are powerful, but not immediately obvious. This post takes a closer look at the new functionality.
