Dear all,
I found a wonderful package (vcd) able to plot ternary diagrams, i.e. 
ternaryplot (thanks D. Meyer).
The problem is that one of three variable has negative values.
If I use the ternaryplot function but some points are outside the 
triangle, as value en negative.
Is it possible to make the ternary diagram fit exactly the cloud points ?
