R

R is one of the most used software for data analysis in Social Sciences. Since the best feature of R (besides being open source) is its community, you can find help from every part of the world online. You are never alone, and if you feel lost, you can just ask google to help you.

Everyone can contribute with new packages, by signaling bugs in existing packages, opening issues in GitHub, suggesting new features, and so forth.

This course

This course aims at giving a brief yet comprehensive introduction to the use of R as a programming language. R can be used for developing web applications through RStudio and the shiny package. Some examples of shiny apps can be found here.
