Info

Software requirements

You should have both R and RStudio installed on your machine.

In this workshop, we will be using R together with the integrated development environment (IDE) RStudio. In addition to offering a "cleaner" programming development than the basic R editor, RStudio offers a large number of added functionalities for integrating code into documents, built-in tools and web-development.

Prerequisites

There are no formal prerequisites for this workshop. However, I am assuming that participants have a basic understanding of R programming, in particular:

  • Setting a working directory,
  • Installing and loading packages,
  • Reading and writing data,
  • Basic data formats (scalar, vector, data frame),
  • Basic variable types (numeric, character, factor, logical),
  • Basic vector and data frame operations, such as subsetting, transforming variables, merging, reshaping, etc.

If you are unfamiliar with R or would like to brush up on your skills, take a look at my intro to data management workshop. The first two sessions go over basic R functionality and programming principles. The latter four sessions introduce data management operations using packages from the tidyverse suite. I also recommend taking a look at R for Data Science website and/or book for a great resource on learning R and data management.

Getting help

The key to learning R is: Google! This workshop will give you an overview over data visualiztion in R, but to become truly proficient you will have to actively use it yourself, trouble shoot, ask questions, and google! The R mailing list and other help pages such as StackOverflow offer a rich archive of questions and answers by the R community. For example, if you google "recode variable in r" you will find a variety of useful websites explaining how to do this on the first page of the search results. Also, don't be surprised if you find a variety of different ways to execute the same task.

RStudio has a useful help menu. In addition, you can get information on any function or integrated data set in R through the console, for example:

??geom_tile
