Convert Tessellation to Data Frame
Converts a spatial tessellation object to a data frame.
## S3 method for class 'tess' as.data.frame(x, ...)

This function converts the tessellation x to a data frame.
If x is a pixel image tessellation (a pixel image with factor
values specifying the tile membership of each pixel) then this
pixel image is converted to a data frame by
as.data.frame.im. The result is a data frame with
columns x and y giving the pixel coordinates,
and Tile identifying the tile containing the pixel.
If x is a tessellation consisting of a rectangular grid of tiles
or a list of polygonal tiles, then each tile is converted to a
data frame by as.data.frame.owin, and these data frames
are joined together, yielding a single large data frame containing
columns x, y giving the coordinates of vertices of the
polygons, and Tile identifying the tile.
A data frame with columns named x, y, Tile,
and possibly other columns.
