⚠️There's a newer version (1.3.1) of this package.Take me there.

StratigrapheR (version 1.0.1)

Integrated Stratigraphy

Description

Includes bases for litholog generation: graphical functions based on R base graphics, interval management functions and svg importation functions among others. Also include stereographic projection functions, and other functions made to deal with large datasets while keeping options to get into the details of the data. When using for publication please cite Wouters, S., Da Silva, A.C.
