Data science is 90% cleaning the data and 10% complaining about cleaning the data.
In the realm of data wrangling, data.table from R and pandas from Python dominate. This repo is meant to be a comprehensive, easy to use reference guide on how to do common operations with data.table and pandas, including a cross-reference between them as well as speed comparisons.
This repo consists of three primary directories:
The Python and R directories each contain three similarly structured files:
The wrangle files make use of four datasets in the Data directory:
These datasets are small for illustrative purposes. If you'd like to test speed comparisons between pandas and data.table, you can use the make_data.R file to generate large versions of these datasets.
I'd like to encourage contributions for this project - it's well suited for it. Also note that I'm much more comfortable using data.table than pandas, so it's likely I've done some suboptimal wrangling in pandas.
