About me

My experiences with R

Why I moved to Python

Whats so good about Python


About meCompleted a PhD in statistical genetics at

University of Reading in 2008

Worked at Smartodds from 2007 to 2011

Setup Global Sports Statistics in 2011


My experiences with RInitially used R at PhD level integrated with

C to do analysis

R was the primary programming language once I started work

R used for data analysis and maintenance tasks


Why I moved to pythonR was used due to the ease of data

manipulation and large statistical library

However R was also being used for other tasks such web scraping and html/xml parsing

R was becoming the only choice used for scripting


Why I moved to python

I first used python for an XML parsing task

Code was easy to write

Results were great

This got me curious about what else Python had to offer


Dive into Python

To learn more about Python I read “Dive into Python”

Syntactically and stylistically Python was much different to R

The more I learnt the more I used it


Setting up by myself

In 2011 Global Sports Statistics was created

Everything had to be setup from scratch

Used the opporunity to do something different


Why Change?

Development is faster in Python

Easy to write Object Orientated code

Fantastic Library of packages

Sometimes a change is good!


What Python has to offer

Pandas: Data Analysis Library

Django: High Level Web Framework

NumPy: Package for numerical computing

SciPy: Routines for numerical Integration and Optimization


What Python has to offer

Matplotlib: 2-D plotting

Flask: Microframework

Mechanize: Programatic Web Browsring

BeautifulSoup: Html Scraping

PyQt: GUI building


Rpy2

But what if you want to use an R package

Rpy2 allows use of any R functionality from within Python

It also supports use of any packages that R has to offer


Why move to Python

Im not saying you need to

However I believe a lot of what people do in R can be done faster in Python

Try it out whats the worst that can happen?


Thank you for you attention
