Most data-sets in this directory consist of (x,y) pairs giving the locations of a set of events within a designated planar region. In most case, the region is a rectangle, often the unit square. Files are to be read row-wise. Brief explanatory information on some of the data-sets can be found in an associated plain text file, named mnemonically, so for example the explanatory information for "benes.txt" is in "benes_explain.txt" Where there is no explanatory information, the data are most likely described in my book on spatial and spatio-temporal point pattern analysis: Diggle, P.J. (2013). Statistical Analysis of Spatial and Spatio-Temporal Point Patterns (third edition). Boca Raton: Chapman and Hall/CRC Press Some of the data-sets described in the book have not been included for reasons of confidentiality.
