venn.tess {spatstat} | R Documentation |
Given a list of windows, construct the tessellation formed by all combinations of inclusion/exclusion of these windows.
venn.tess(..., window = NULL)
... |
Sets which delimit the tessellation.
Any number of windows (objects of class |
window |
Optional. The bounding window of the resulting tessellation.
If not specified, the default is the union of all the
arguments |
The arguments ...
may be any number of windows.
This function constructs a tessellation, like a Venn diagram,
whose boundaries are made up of the boundaries of these sets.
Each tile of the tessellation is defined by one of the
possible combinations in which each set is either included or
excluded.
If the arguments ...
are named, then the resulting tiles
will also have names, which identify the inclusion/exclusion
combinations defining each tile. See the Examples.
A tessellation (object of class "tess"
).
