This is Ridian, R in Obs idian

literal programming with R notebooks, and Quarto rendering from within Obsidian:

Check out he website:

Up to date info and install guide on the Ridian website

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)

Disclosures and Issues:

[!NOTE]

Seculity Disclosures:

Calls on External Executables: This plugin Executes code in R, an external intepreter, code execution comes with risk, you should at altimes know whether the code is save, don't execute untrusted code. File Access: The plugin accesses temporary directories to store plots and widgets, which are then copied the Obsidian vault under the plots/ and widgets/ folders.

[!NOTE] Known Issues/To-Do:

1. uses absolute paths for htmlwidgets
2. Every note spins up an R process, if you do this for many notes you'll overwhlm memory
3. Only confirmed to work on MacOS on my mackbook & on Win 11's (on my macbook)
4. No tests and other development necessities implemented
5. No Contribution guilines (but help wanted!)

📥 Ridian: Manual Installation Guide for Obsidian

Here's a step-by-step guide to installing your Obsidian plugin, Ridian, using the BRAT (Beta Reviewers Auto-update Tool) plugin. This guide assumes you have Obsidian and BRAT already installed.

R package Dependecies: In R/Rstudio Install: languageserver, evaluate, jsonlite & htmlwidgets packages.

In R/Rstudio Install:

install.packages("evaluate")
install.packages("jsonlite")
install.packages("htmlwidgets")
install.packages("languageserver")

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

After you set the path Ridian will adjust it for internal use (it might look different if you revisit the plugin.

Install pandoc (https://pandoc.org) and point Ridian to your pandoc install if you want to use htmlwidgets in R.

And that’s it! You now have Ridian installed and ready to use in Obsidian via BRAT.
