The recommend installation of ptR is to use one of the prebuilt packages shown found to the left. But prior to installing, there are a few required dependencies that should be installed.

Pre-Installation (Requirements)

• R version 4.0.2 or greater is required. If not already installed, install R
• Pandoc is required. This means doing either 1. or 2. below
  1. install pandoc (and placing it on your path)
  2. install RStudio (RStudio contains a copy of pandoc)

Installation (Using the Installer)

• Choose the button on the left which matches your OS to download the appropriate installer.
• After downloading, double click on the installer and be patient. Note: I have not yet purchased digital signatures, so you may be prompted with a warning. Please ignore.

Post-Installation (First time running)

• Upon opening, ptR will look for additiona R-packages that it requires. If some of these packages are missing, you will be prompted to either quit or let ptR install them for you. When completed, the ptR IDE will start.

Note, pandoc is used for knitr and is normally included in the Rstudio installation.

The Relationship Between pointR and ptR

• pointR is an R package providing a shiny-based minimalist IDE for R scripting using svgR. pointR is primarly written in R, with a little bit of javascript for seasoning.
• ptR is an Electron wrapper around pointR.
• Benefits of using the Electron wrapper:
  • Remove potential hiccups by removing and dependency on the local browser
  • Provide independent windows for help
  • Provide an integrated approach for building shiny custom inputs
