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.
You can install the released version of procmaps from CRAN with:
install.packages("procmaps")
This is what /proc/self/maps looks like (on Linux) when
this document is rendered:
