If a tessellation is plotted in the graphics window, then each time the left mouse button is pressed, this function will find the tile which contains the mouse position, and print its mark value (or its serial number if there is no mark).
# S3 method for tess
identify(x, ...,
labels=tilenames(x),
n=nobjects(x), plot=TRUE, paint=plot, paint.args=list())A data.frame with columns id and name
containing the serial numbers and names of the tiles of
x that were identified, in the order that they were identified;
If x is marked, subsequent columns contain the marks for these tiles.
A tessellation
(object of class "tess").
Arguments passed to plot.owin
and text.default controlling the graphical
display.
Labels associated with the tiles, to be plotted when the
tiles are identified. A character vector or numeric vector
of length equal to the number of tiles in x.
Maximum number of tiles to be identified.
Logical. Whether to plot the labels when a tile is identified.
Logical. Whether to redraw each identified tile, using a different colour.
Optional list of arguments passed to plot.owin determining the
colour and style in which each identified tile will be
redrawn, if paint=TRUE.

This is a method for the generic function identify
for tessellation objects.
The tessellation x should first be plotted
using plot.tess.
Then identify(x)
reads the position of the graphics pointer each time the
left mouse button is pressed. It then determines which tile of
x contains the mouse position.
The index of this tile (and its mark if any)
will be returned as part of the value of the call.
Each time a tile is identified, the tile will be plotted in light blue fill colour, and text will be displayed inside the tile showing the name of the tile.
