Up to date info and install guide: [https://michelnivard.github.io/Ridian/]

What this is:

• A way to run R code in Obsidian

• Full Quarto compliant code chunk processing (allows for seamless transition to other editors)

• Parse a note and make it Quarto compliant, then render with Quarto

• A way to keep notes on Coding/Statistics with enbedded working example

• A way to use Obsidians amazingsearch and links to link code snippets

• A way to use R code snippets to add plots/widgets to your notes

What this won't be:

• An Rstudio replacement

• an positro replacement

• It wont cover other programming languages (5% chance of python), here is an excelent option for that: execute code plugin

Important

In the Ridian settings provide the path to your R/pandoc/quarto executables, The R executable can for example be at Mac: /usr/local/bin/R Windows: C:\Program Files (x86)\R\R-4.4.1\bin\R.exe

The plugin will try to guess the R install (and probably fail)
