Description
Portable Address Space Mapping.
Description
Portable '/proc/self/maps' as a data frame. Determine which library or other region is mapped to a specific address of a process. -- R packages can contain native code, compiled to shared libraries at build or installation time. When loaded, each shared library occupies a portion of the address space of the main process. When only a machine instruction pointer is available (e.g. from a backtrace during error inspection or profiling), the address space map determines which library this instruction pointer corresponds to.

procmaps
The goal of procmaps is to help determine which library or other region is mapped to a specific address of a process. It is the equivalent of /proc/self/maps as a data frame, and is designed to work on all major platforms.
Installation
You can install the released version of procmaps from CRAN with:
install.packages("procmaps")
Example
This is what /proc/self/maps looks like (on Linux) when this document is rendered:

Other operating systems make this information available in other form. This package provides the equivalent as a data frame, regardless of operating system:
