⚠️There's a newer version (2.1.0) of this package.Take me there.
rysgran (version 2.0)
Grain size analysis, textural classifications and distribution
of unconsolidated sediments
Description
This package is a port to R of the SysGran program,
written in Delphi by Camargo (2006). It contains functions for
the analysis of grain size samples (in logarithmic (phi) and
geometric (micrometers) scale) based on various methods, like
Folk & Ward (1957) and Methods of Moments (Tanner, 1995), among
others; textural classifications and distribution of
unconsolidated sediments are shown in histograms, bivariated
plots and ternary diagrams of Shepard (1954) and Pejrup (1988).
English and Portuguese languages are supported in outputs
