Extracts the boundary edges of a window and returns them as a line segment pattern.
edges(x, ..., window = NULL, check = FALSE)
- A window (object of class
"owin"), or data acceptable to
as.owin, specifying the window whose boundary is to be extracted.
- Window to contain the resulting line segments.
- Logical. Whether to check the validity of the resulting segment pattern.
The boundary edges of the window
x will be extracted as a line
- A line segment pattern (object of class
perimeter for calculating the total length of the boundary.
