\begin{Description}\relax
The \code{cav} data frame has 138 rows and 2 columns.


The data gives the positions of the individual caveolae in a square region
with sides of length 500 units.  This grid was originally on a 2.65mum
square of muscle fibre.  The data are those points falling in the lower left 
hand quarter of the region used for the
dataset \code{caveolae.dat} in the \code{spatial} library by B.D. Ripley (1994) which
is available from Statlib
