Python & R resources

Here is a quite extensive list of useful links for learning  R and Python. Most of them are free, but you will also find good books that I have found useful. For sure, R and Python are both valuable programming languages for scientists. The R language has its focus on statistical computing whereas Python is a more general-purpose language.

R programming


The Comprehensive R Archive Network – Here you will find a lot of information and pre-compiled binaries for most operation systems.

Rstudio is the IDE (Integrated development environment) that I find most useful.

Python programming language

Integrated Development Environments (IDE)

Scrapy – An easy-to-use open-source (and of course free) tool for extracting data from the web (see my post)

Spyder – a very useful Python IDE. It offers similar functionalities as RStudio. It is a Scientific PYthon Development EnviRonment!

Rodeo – An IDE that is very similar to RStudio.

See my post RStudio-like Python IDEs – Rodeo & Spyder for more information on both Rodeo and Spyder.

Experiment building software

PsychoPy – Free and Open Source Experiment builder written in Python. With PsychoPy you can create experiments by writing your own Python scripts or using its drag-and-drop graphical interface.

Expyriment is more like a library for making generation of experiments easier than using plain Python.

OpenSesame supports, much like PsychoPy, both Python scripting and a graphical interface for creating experiments. OpenSesame lets you choose which back-end you want use. Therefore, the application offer the same functionality as PsychoPy (back-end “Psycho”), Expyriment (back-end Xpyriment) and more (e.g.m OpenGL).

If you are interested in more about all the above mentioned applications (and more) see my posts: Python apps and libraries for creating experiments and Free & Useful Software – PsychoPy.

Pandas Resources:

Pandas is a great package that makes data manipulation, descriptive statistics, data visualization, amongst other things very easy to perform, Below are some Pandas dataframe tutorials, how to read and write data (e.g., SPSS, Excel, CSV, HTML tables, and JSON files).

Jobs and Hiring

In this section, you will find useful links and resources related to both searching for jobs as a Python or R developer, data scientist, or where the two programming languages are sought for.


Now, if you are running a company there are plenty of things to consider when hiring a programmer. The resources you will find here are mainly things I’ve found interesting. That is, I don’t have any experience hiring staff.
