plotmaskedge

Outline Around Mask Cells

Plots the outer edge of a mask.

plotMaskEdge(mask, plt = TRUE, add = FALSE, ...)

`mask`	secr habitat mask object
`plt`	logical; if TRUE the edge is plotted
`add`	logical; if TRUE the line is added to an existing plot
`...`	other line plotting arguments passed to `segments`

May be slow.

A numeric matrix of 4 columns is returned invisibly. The columns may be used as arguments x0, y0, x1, y1 in a call to segments().

A bug in secr <3.2.2 caused some internal lines to appear when the mask spacing was not an integer.

## Not run:
