5 DataFramesMeta.jl

In this chapter we’ll cover DataFramesMeta.jl, a package that uses convenient data wrangling syntax translating to DataFrames.jl commands. The syntax is similar to the dplyr package from R’s tidyverse. Compared to using pure DataFrames.jl, DataFramesMeta.jl commands are typically more convenient to write and more similar to dplyr which makes DataFramesMeta.jl particularly suitable for people familiar with the R programming language.

A major advantage of DataFramesMeta.jl is that, contrary to dplyr, there are fewer commands that you need to learn. Specifically we’ll cover 6 commands:

• @select: column selection
• @transform: column transformation
• @subset: row selection
• @orderby: row sorting
• @combine: data summaries
• @chain: piping operations
