Ternary plots made simple. This package allows to create
ternary plots using 'graphics'. It provides functions to display the
data in the ternary space, to add or tune graphical elements and to
display statistical summaries. It also includes common ternary
diagrams which are useful for the archaeologist (e.g. soil texture
charts, ceramic phase diagram).
