September 8, 2020 - Official site for the Data Wrangling with DataFrames.jl Cheat Sheet.

A simple cheatsheet indicating how most of the commands in the dplyr cheatsheet, translate into a combination of DataFrames.jl and Julia commands. The aim here is to rely solely on the DataFrames.jl approach, there are however, adscititious packages such as Chain.jl and DataFramesMeta facilitating a more dplyr-like workflow.

Impute.jl: various methods for handling missing data in vectors, matrices and tables. DataFramesMeta.jl: A range of convenience functions for DataFrames.jl that augment select and transform to provide a user experience similar to that provided by dplyr in R.

A DataFrames.jl tutorial.

This resource aims to teach you everything you need to know to get up and running with tabular data manipulation using the DataFrames.jl package.

The table below describes the correspondence between DataFramesMeta.jl macros and the function that is actually called by the macro. This can be done in two ways. When inputs are given as multiple arguments, they are added at the end after a semi-colon ;, as in · julia> df = DataFrame(x = [1, 1, 2, 2], b = [5, 6, 7, 8]); julia> @rsubset(df, :x == 1 ; view = true) 2×2 SubDataFrame Row │ x b │ Int64 Int64 ─────┼────────────── 1 │ 1 5 2 │ 1 6

Hence, for example, if the user wants to change the color of all numbers smaller than 0 to red in Jupyter, they can execute: show(stdout, MIME("text/html"), df; highlighters = hl_lt(0, HtmlDecoration(color = "red"))) after using PrettyTables. For more information about the available options, check PrettyTables.jl documentation. Objects of the DataFrame type represent a data table as a series of vectors, each corresponding to a column or variable.

January 27, 2021 - You can use (my own utility module) LAJuliaUtils.jl in order to Pivot and optionally filter and sort in a single function in a spreadsheet-like Pivot Tables fashion. See the relevant section. CSV.write("file.csv", df, delim = ';', header = true) (from package CSV) ... This export to a dictionary where the keys are the unique elements of a df column and the values are the splitted dataframes:

In the rest of this chapter, we will show you how you can easily answer these questions in Julia. To do so, we first show why we need a Julia package called DataFrames.jl.

Before we wrap up let us discuss the empty and empty! functions that remove all rows from a DataFrame. Understanding the difference between the behavior of these two functions will help you to understand the function naming scheme in DataFrames.jl in general.
