%description
Reads and writes 'ARFF' files. 'ARFF' (Attribute-Relation File Format)
files are like 'CSV' files, with a little bit of added meta information in
a header and standardized NA values. They are quite often used for machine
learning data sets and were introduced for the 'WEKA' machine learning
'Java' toolbox. See
<https://waikato.github.io/weka-wiki/formats_and_processing/arff_stable/>
for further info on 'ARFF' and for <http://www.cs.waikato.ac.nz/ml/weka/>
for more info on 'WEKA'. 'farff' gets rid of the 'Java' dependency that
'RWeka' enforces, and it is at least a faster reader (for bigger files).
It uses 'readr' as parser back-end for the data section of the 'ARFF'
file. Consistency with 'RWeka' is tested on 'Github' and 'Travis CI' with
hundreds of 'ARFF' files from 'OpenML'.
