**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**. Finally, R is a complete, interactive, and 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.

You may want to start with R commander. It provides a menu which may make learning R a bit easier at the beginning. R can be downloaded here: The Comprehensive R Archive Network.

## R resources

One of the main things that I like with R is the broad and helpful community. This also means that there are many good resources for learning the language.

### General

When starting off learning R any source may be useful. Here are some of the best R learning resources I’ve used:

- Quick-R: A comprehensive source for information on how to carry out many common statistical analysis as well as
**descriptive statistics**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 “blog 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.

### Psychology

If you are a psychology researcher aiming to learn R it can be helpful to learn from other psychologists more experienced with the R statistical language. There are also some r-packages that are developed for psychology researchers.

- Using R for Psychological Research – here you will find many tutorials for using R in psychological research. These are very pedagogical and helpful. Here you also find the homepage of the great r-package
*psych*. - Notes on the use of R for psychology experiments and questionnaires
- Learning Statistics with R
**free**draft of a book for learning R. It mainly covers**frequentists**methods but have a 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**). - The Psycho Blog. Here you will find some great blog posts and a very useful R-package called Psycho.R! It will make doing some of the most common statistical methods in Psychology easy to carry out using R.

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.
