Description
The crimerate dataset provides crime rates per 100,000 people in
seven categories for each of the fifty states (USA) in 1977. The timage12 dataset
is an image from fMRI analysis (one brain slice), it is a t-statistic image over 12 subjects of the activation (verbal) parameter.
The Zone_climTUN is an object of class Map representing montly (12) measurements in Tunisia
of 10 climatic indicators. The grid of 2599 cells was stored previously as a shapefile and read using read.shape.
Usage
