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) which is part of the recommended 'VR' bundle. _U_s_a_g_e: cav _F_o_r_m_a_t: This data frame contains the following columns: '_x' The x coordinate of the caveola's position in the region. '_y' The y coordinate of the caveola's position in the region. _R_e_f_e_r_e_n_c_e_s: Appleyard, S.T., Witkowski, J.A., Ripley, B.D., Shotton, D.M. and Dubowicz, V.
