# UCI Machine Learning datasets for R
Andrzej Wójtowicz  



Document generation date: 2016-08-19 21:47:14.

This project preprocesses a few datasets from [UC Irvine Machine Learning
Repository](https://archive.ics.uci.edu/ml/) into tidy R object files.
It focuses on the binary classification datasets and saves only complete cases
within a dataset.

**R software**: [Microsoft R Open](https://mran.microsoft.com/open/) (3.3.0)

**Reproducibility library**: [checkpoint](https://github.com/RevolutionAnalytics/checkpoint)

**Reproducibility procedure**:

 1. Run *s1-download-data.R* to download original datasets.
 2. Run *s2-preprocess-data.R* to preprocess the datasets.
 
 Optionally:
 
 3. knit *s3-make-readme.Rmd* to get an overview of the preprocessed datasets,
 4. run *s4-make-release.sh* to create zip file with preprocessed datasets.
