DataFrames.jl Overview

The DataFrames package provides the essential tools you need for working with statistical data in Julia.

In particular, DataFrames provides:

  • NA: A new Julia type that represents a missing value
  • DataArray: A new Julia type that emulates Julia’s standard Array type, but adds the ability to store missing values in the array
  • DataFrame: A new Julia type that represents tabular datasets like those found in typical databases or spreadsheets
