# 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.
