Plot a soil texture data table as points on an existing texture 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
        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.
