Visualize the structure of a R project/package?

I am trying to write a package to have a common interface to several, related R projects. One of them is a R package, the other two just a collection of R scripts. Before writing any code, I'd like to better understand the structure of each in order to understand similarities and differences.

Is there a way (i.e., package) to visualize (e.g., tree) their structure? For instance, a tree showing which function calls which. Thanks.

Hi @lorenzoF,
Welcome to the RStudio Community Forum.

A quick Google search for "dependency tree in R" and "Visualizing R Function Dependencies" will give you many useful hits.
