BIS180LTutorials

This repository contains some learnr interactive tutorials for R.

There are currently four tutorials:

• "Tidyverse_Introduction" introduces concepts and tools important for using tidyverse packages.
• "ggplot" teaches basic ggplot2 plotting skills
• "Gather_And_Spread" focuses on converting data between long and wide formats (deprecated, use Pivot)
• "Pivot" focuses on converting data between long and wide formats
• "Joins" illustrates how to join multiple data frames based on shared keys
• "Stringr_and_Regex" Introduced regular expressions and string manipulation with the stringr package.

Installing the tutorials

First you need to have learnr and devtools installed.

From within R:

#only needs to be done once per computer
install.packages("learnr")
install.packages("devtools")

Then install the tutorials themselves:

devtools::install_github("UCDBIS180L/BIS180LTutorials") # only needs to be done once per computer

Starting the tutorials

When you want to actually use the tutorial, then:

learnr::run_tutorial("TUTORIAL_NAME", package = "BIS180LTutorials") 

where "TUTORIAL_NAME" gets replaced by one of "Tidyverse_Introduction", "ggplot", "Gather_And_Spread", or "Joins". (keep the quotes).

Additional resources

The material introduced in these tutorials is covered in much more detail in R for data science by Garrett Grolemund and Hadley Wickham

Serving the tutorials

If you want to serve the tutorials on a shiny server instance, then:

• be sure that the directory containing the tutorials is owned by shiny
• delete the .html file associated with each tutorial
