Good resources for learning R as a Psychologist are hard to find. By that I mean that there are so many great sites and blogs around the internet to learn R. Thus, it may be hard to find learning resources that targets Psychology researchers. Recently I wrote about 4 good R books targeted for Psychology students and researchers (i.e., R books for Psychologists). There are, however, of course other good resources for Psychological researchers to learn R programming. Therefore, this post will list some of the best blogs and sites to learn R. The post will be divided into two categories; general and Psychology focused R sites and blogs. For those who are not familiar with R I will start with a brief introduction on what R is (if you know R already;click here to skip to the links).
What is R?
R is a free and open source programming language and environment. Data analysis in R is carried out by writing scripts and functions. R is a complete, interactive, object-oriented language.
In R statistical environment you are able to carry out a variety of statistical and graphical techniques. For instance, linear and nonlinear modeling, classical statistical tests, time-series analysis, classification, and many more can be carried using both frequentist and bayesian paradigms.
R has a broad and helpful community and, therefore, there are many good resources for learning the language.
- Quick-R: A comprehensive source for information on how to carry out many common statistical analysis as well as descriptives and graphs.
- SimpleR notes for introducing the use of R for an introductory statistics course.
- The R Guide
- Cookbook for R provides solutions to many tasks and problems in data analysis.
- Revolution Analytics – A blog for news and information about R. Publishes guides and articles about R.
- R-bloggers A “blogg aggregator” for R blogs. Here you can find, and follow, a lot of comprehensive, basic and advanced, guides and posts.
- RStudio – my Integrated Development Environment (IDE) of choice when it comes to R.
- Using R for Psychological Research – here you will find many tutorials for using R in psychological research. These are very pedagogical and helpful. Also homepage of the r-package psych.
- Notes on the use of R for psychology experiments and questionnaires
- Learning Statistics with R free book for learning R. Mainly covers frequentists methods but have one chapter of Bayesian statistics.
- Psychometric Models and Methods a brief overview of packages that are closely related to psychometrics. Used to teach statistics to Psychology students.
- Mixed Psychophysics – aims to give statistical tools (i.e., R code, models, tutorials, and links to articles) for psychophysics. Contains a short tutorial covering Psychometric functions, generalized mixed models (GLMM).
Although, the learning curve for software such as R is steeper than using software with graphical interfaces (i.e., SPSS, Stata, and Statistica) it is not super hard to learn to carry out the most basic and classical statistical tests. If you aim for reproducibility learning R and/or LaTeX or RMarkdown is really the way to go.
