Biological Cells Point Pattern

Description

The data record the locations of the centres of 42 biological cells observed under optical microscopy in a histological section. The microscope field-of-view has been rescaled to the unit square.

The data were recorded by F.H.C. Crick and B.D. Ripley, and analysed in Ripley (1977, 1981) and Diggle (1983). They are often used as a canonical example of an ‘ordered’ point pattern.

Usage

Format
