This function can be used to identify clumps of points in a point pattern.

The function `connected`

is generic. This file documents the methods for
point patterns in dimension two or three (objects of class `"ppp"`

or
`"pp3"`

).

The point pattern `X`

is first converted into an abstract graph
by joining every pair of points that lie closer than `R`

units
apart. Then the connected components of this graph are identified.

Two points in `X`

belong to the same connected component if they
can be reached by a series of steps between points of `X`

,
each step being shorter than `R`

units in length.

The result is a vector of labels for the points of `X`

where all the points in a connected component have the same label.

A point pattern, equivalent to `X`

except that the points
have factor-valued marks, with levels corresponding to the
connected components.
