The 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 caveolae.dat in the spatial package by B.D. Ripley (1994).
cavThis data frame contains the following columns:
xThe x coordinate of the caveola's position in the region.
yThe y coordinate of the caveola's position in the region.
