# Plot contours of equal symmetric difference on a ternary plot

Source:`R/TernaryPoints.R`

`SymmetricDifferenceLineEnds.Rd`

Assumes that tree 1 is perfectly resolved, but that the resolution of tree 2 can vary.

## Arguments

- nsd
Vector specifying normalized symmetric differences to plot.

- ...
Further parameters to pass to

`TernaryLines()`

.

## Value

Returns a matrix of dim `(length(nsd), 6)`

, with columns named
`r2a`

, `da`

, `sa`

, `r2b`

, `db`

and `sb`

.
Lines from `a`

to `b`

in each row connect points of equal symmetric difference.
