Setting up your computer for WORCS

This is a tutorial on how to set up your personal computer for use with the worcs package. It guides you through the installation of several software packages, and registration on GitHub. This vignette does not assume a prior installation of R, so it is suitable for novice users. You only have to perform these steps once for every computer you intend to use R and worcs on, and the entire process should take approximately 30 minutes if you start from scratch. In case some of the software is already installed on your system, you can skip those related steps.

Follow these steps in order:

1. Install R (free)
2. Install ‘RStudio’ Desktop (Free)
3. Install Git from git-scm.com. Use the default, recommended settings. It is especially important to leave these settings selected:
   • Git from the command line and also from third party software
     
   • Use the ‘OpenSSL’ library
     
   • Checkout Windows-style, commit Unix-style line endings
     
   • Enable Git Credential Manager
     
   • If you run into any trouble, a more comprehensive tutorial on installing Git is available at happygitwithr.com.
4. Register on ‘GitHub’ (alternatively: see this vignette on how to use ‘GitLab’ or ‘Bitbucket’)
   • Go to github.com and click Sign up. Choose an “Individual”, “Free” plan.
5. Install all packages required for WORCS by running the code block below this writing in the ‘RStudio’ console. Be prepared for three contingencies:
   • If you receive any error saying There is no package called [package name], then run the code install.packages("package name")
     
   • If you are prompted to update packages, just press [ENTER] to avoid updating packages. Updating packages this way in an interactive session sometimes leads to errors if the packages are loaded.
     
   • If you see a pop-up dialog asking Do you want to install from sources the package which needs compilation?, click No.

install.packages("worcs", dependencies = TRUE)
tinytex::install_tinytex()
renv::consent(provided = TRUE)

6. Connect ‘RStudio’ to Git and GitHub (for more support, see Happy Git with R
   1. Open ‘RStudio’, open the Tools menu, click Global Options, and click Git/SVN
   2. Verify that Enable version control interface for RStudio projects is selected
   3. Verify that Git executable: shows the location of git.exe. If it is missing, manually fix the location of the file.
   4. Restart your computer
   5. Run usethis::create_github_token(). This should open a webpage with a dialog that allows you to create a Personal Access Token (PAT) to authorize your computer to exchange information with your GitHub account. The default settings are fine; just click “Generate Token” (bottom of the page).
   6. Copy the generated PAT to your clipboard (NOTE: You will not be able to view it again!)
   7. Run gitcreds::gitcreds_set(). This should open a dialog in the R console that allows you to paste the PAT from your clipboard.
   8. If you do not have a Git user set up on your computer yet (e.g., if this is the first time you will be using Git), run the following - making sure to substitute your actual username and email:

worcs::git_user("your_name", "your_email", overwrite = TRUE)

7. Everything should be installed and connected now. You can verify your installation using an automated test suite. The results will be printed to the console; if any tests fail, you will see a hint for how to resolve it. Run the code below this writing in the ‘RStudio’ console:

worcs::check_worcs_installation()

install.packages("papaja", dependencies = TRUE, update = "never")
