UCI Machine Learning datasets for R

Andrzej Wójtowicz

Document generation date: 2016-07-17 02:59:19.

This project preprocesses a few datasets from UC Irvine Machine Learning Repository 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 (3.2.5)

Reproducibility library: checkpoint

Reproducibility procedure:

1. Run s1-download-data.R to download original datasets.
2. Run s2-preprocess-data.R to preprocess the datasets.
3. Optionally knit s3-make-readme.Rmd to get an overview of the preprocessed datasets.

Table of Contents

1. Bank Marketing
2. Breast Cancer Wisconsin (Diagnostic)
3. Breast Cancer Wisconsin (Original)
4. Cardiotocography
5. Default of credit card clients
6. ILPD (Indian Liver Patient Dataset)
7. MAGIC Gamma Telescope
8. Seismic bumps
9. Spambase
10. Wine Quality
