keywords: ["R", "subset", "data.frame", "read.csv", "dplyr", "ggplot2"]

This is an introduction to R designed for participants with no programming experience. These lessons can be taught in 3/4 of a day (6 hours). They start with some basic information about syntax for the R programming language, the RStudio interface, and move through to specific programming tasks, such as importing CSV files, the structure of data frame objects in R, dealing with categorical variables (i.e. factors), basic data manipulation (adding/removing rows and columns), and finishing with calculating summary statistics and a brief introduction to plotting. There is also a lesson on how to use databases from R that is intended to be taught after the SQL lesson, and ideally at the end of a Data Carpentry workshop.
- Having R and RStudio installed (though see the first lesson, Before we start for installation instructions)
- Before we start
- Introduction to R
- Starting with data
- Aggregating and analyzing data with dplyr
- Data visualization with ggplot2
- R and Databases
There is "code handout" (code-handout.R) that is intended to
be distributed to the participants. This file includes some of the examples used
during teaching and the titles of the section. It provides a guide that the
participants can fill in as the lesson progresses. Participants can also source
code from this file to avoid typos in more complex examples.
