TT.classes.tbl

class.sys

collapse

Returns the table of classes of a texture classification system. 
Returns the classes abbreviations, names and the vertices numbers 
that defines each class. Use TT.vertices.tbl() to retrieve the 
clay silt sand coordinates of the triangle classes vertices. 
See also TT.vertices.plot().

"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
        triangles "Bodenkundliche Kartieranleitung 1994", "SEA 1974"
        and "TGL 1985"; Soil Survey of England and Wales; Australian
        triangle; Belgian triangle; Canadian triangle; ISSS triangle;
        Romanian triangle; Polish triangle.

TT.classes.tbl: Returns the table of classes of a texture classification system.
