Metaprogramming tools for DataFrames.jl objects to provide more convenient syntax. DataFrames.jl has the functions select, transform, and combine, as well as the in-place select! and transform! for manipulating data frames. DataFramesMeta.jl provides the macros @select, @transform, @combine, @select!, and @transform! to mirror these functions with more convenient syntax. Inspired by dplyr in R and LINQ in C#.
Features
- To reference columns inside DataFramesMeta macros, use Symbols
- Examples available
- Column selections and transformations
- Summarize, or collapse, a grouped data frame by performing transformations at the group level
- Sort rows in a DataFrame by values in one of several columns or a transformation of columns
- Rename columns in a data frame using the keyword argument-like syntax
