Understanding complex R objects with tools similar to str()
C
lobstr provides tools for inspecting the internal structure of R objects, going beyond what str() offers. It helps developers understand how R represents and stores data at a low level.
The package includes three main capabilities: visualizing abstract syntax trees of R expressions with ast(), examining object references and memory sharing with ref() and obj_size(), and displaying call stack relationships with cst(). These tools are particularly useful for understanding R’s memory management, debugging complex data structures, and learning how R evaluates code. The package reveals internal details that are typically hidden from users.
