TT.data.test.X

Test the validity of some soil texture data table. (1) Test that it is a
data.frame or matrix, (3) Test that there are no missing values, (4) that
all values are &gt;= 0, (5) That the sum of the X particle size class is &gt;=
'text.sum'*(1-'text.tol') or &lt;= 'text.sum'*(1+'text.tol'). Contrary to
TT.data.test() no test are performed for the particle size classes and
columns names, so 'tri.data' should only contains texture data, and nothing
else.

"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. Many (> 15) texture triangles from all around the world are predefined in the package. A simple text based graphical user interface is provided: soiltexture_gui().
