r-fuzzywuzzyR

Fuzzy String Matching.

fuzzywuzzyR

The fuzzywuzzyR package is a fuzzy string matching implementation of the fuzzywuzzy python package. It uses the Levenshtein Distance to calculate the differences between sequences. More details on the functionality of fuzzywuzzyR can be found in the blog-post and in the package Vignette.

UPDATE 26-07-2018: A Singularity image file is available in case that someone intends to run fuzzywuzzyR on Ubuntu Linux (locally or in a cloud instance) with all package requirements pre-installed. This allows the user to utilize the fuzzywuzzyR package without having to spend time on the installation process.

System Requirements

• Python (>= 2.4)

• difflib

• fuzzywuzzy ( >=0.15.0 )

• python-Levenshtein ( >=0.12.0, optional, provides a 4-10x speedup in String Matching, though may result in differing results for certain cases)

Before the installation of any python modules one should check the python-configuration using :

reticulate::py_config()

All modules should be installed in the default python configuration (the configuration that the R-session displays as default), otherwise errors will occur during package installation.

Debian/Ubuntu/Fedora

Python2

sudo apt-get install python-pip
sudo pip install --upgrade pip
pip install fuzzywuzzy
pip install python-Levenshtein

Python 3

sudo apt-get install python3-pip
sudo pip3 install --upgrade pip
pip3 install fuzzywuzzy
pip3 install python-Levenshtein

Macintosh OSX

sudo easy_install pip
sudo pip install fuzzywuzzy
sudo pip install python-Levenshtein

Windows OS

• Download of get-pip.py
• Update of the Environment variables ( Control Panel >> System and Security >> System >> Advanced system settings >> Environment variables >> System variables >> Path >> Edit ) by adding ( for instance in case of python 2.7 ) :

C:\Python27;C:\Python27\Scripts

• Install the Build Tools for Visual Studio
• Open the Command prompt and use the following commands:

pip install fuzzywuzzy
pip install python-Levenshtein
