Both the quiet and chaotic state is modelled to be normal distributed. So

For 'VEC' you may not need to do anything -- in
a lot of circumstances it will just work.
For 'VECH' you can write a function using the
'lower.tri' function.
But it seems to me that the assumption behind your

has written is going to be better
The xy.coords function is a powerful function used by a lot of the plotting

a 2 column matrix, or a list with x and y components (and possibly others), but
it does not do 'topleft' and the like. The legend function
