Visualizing How Functions Connect Within an R Package

[KoderKow]

Hello RStudio Community!

I have done some searching on the web and was unable to find a package that does what I am looking for and wanted to see if anyone here knows of a project/process that does this.

If I have a package is there a process out there that lets me give the package as an input and the output would be a diagram of all the internal and external functions and how they are called from one another?

I have been researching the {targets} package and love the diagrams it can generate showing the overall process of a project. That has me starting to think if there is a way to visualize the way my package is structured and what functions depend on other functions.

Thanks in advance!

{ScriptMapR} purports to do this, although it uses Cytoscape as an external rendering engine. At a glance ,Cytoscape appears unnecessarily elaborate and one of the many R graph packages should provide a substitute for exploiting the node-edge lists generated by ScriptMapR.

Probably simpler is {CodeDepends}

In a R-hub blog post I used the pkgapi package by @Gabor, together with visNetwork.

Thanks for sharing these packages! I have not seen any of them before. {ScriptMapR} has problems installing in my work environment so I couldnt test that, from what I saw that package would produce some beautiful displays for scripts. I didn't see anything about a package as a whole.

After installing a few packages from bioconductor, I was able to produce some static plot which were a bit hard to read. However, while scrolling the issues on GitHub I found a reference to a package that does exactly what I am looking for, {pkgnet}! This package will even write out a vignette for my internal packages at work, thanks for sharing all of these packages with me!

That was an amazing post @maelle! I had a blast modifying the code and playing around with {visNetwork} for the first time! I have stumbled upon {pkgnet} which builds wonderful reports based off the current project and creates plots very similar to what you have shared in your post!

Thank you so much for sharing with me!

Nice, thank you for sharing about {pkgnet}!
