Learnr tutorials

Tutorials are available to run through with the R package learnr. These are interactive tutorials that give practice and exercises to supplement this site.

We recommend you run through the learnr tutorials on your own computer with RStudio by following the instructions outside of this box.

However, if you cannot get it to easily work or you prefer you can run it on the course webVNC you were provided (if you are not on the course you will have to run this through your own computer).

To run the tutorial on the webVNC run the following use script on a new terminal:

. useneoftidytuts

Then follow the instructions on the terminal.

Rtools for windows

If you are using a windows machine you will need to have RTools installed. Close your RStudio (or equivalent) and open the below link:

https://cran.r-project.org/bin/windows/Rtools/

  • Click on the the latest version
  • On the new page find and click on the “RToolsXX INstaller” (XX being the number of the version, e.g. 45) to download the installer
  • Run the installer

Once RTools is installed you can open up RStudio and run the below.

Install instructions

You will need R and RStudio installed on your computer.

Within RStudio you will need to install the learnr package and the packages our learnr tutorials require. Below are the R commands to install these.

#learnr
install.packages("learnr")
#tidyverse
install.packages("tidyverse")
#lterdatasample
install.packages("lterdatasampler")
#INstall hexbin
install.packages("hexbin")
#Our packages are available through github rather than cran
#To install github based packages you need to install and load 
# the remotes package
install.packages("remotes")
library("remotes")
#mgrtibbles
remotes::install_github("m-gemmell/mgrtibbles")
#neoftidytutorials
#Package with the tidyverse learnr tutorials
remotes::install_github("m-gemmell/neoftidytutorials")

Libraries

Prior to running any tutorials (next page) you must load the learnr and neoftidytutorials packages in your RStudio.

library("learnr")
library("neoftidytutorials")
