⚠️There's a newer version (1.5.3) of this package.Take me there.
soiltexture (version 1.0)
Functions for soil texture plot, classification and
transformation
Description
"The Soil Texture Wizard" is a set of R functions designed
to produce texture triangles (also called texture plots,
texture diagrams, texture ternary plots), classify and
transform soil textures data. These functions virtually allows
to plot any soil texture triangle / classification into any
triangle geometry (isosceles, right-angled triangles, etc.).
This set of function is expected to be useful to people using
soil textures data from different soil texture classification
or different particle size systems. Several texture triangles
are predefined: USDA; FAO (which is also the triangle for the
soil map of Europe); Aisne (France); GEPPA (France); German
triangle (Bodenkundliche Kartieranleitung 1994); Soil Survey of
England and Wales (UK); Australian triangle; Belgian triangle;
Canadian triangle; ISSS triangle; Romanian traingle. The Soil
Texture Wizard is initially develloped from the functions
'soil.texture()' from the package 'plotrix' by Jim Lemon et al.
