rongelapUTM: Rongelap data

Description

This data-set was used by Diggle, Tawn and Moyeed (1998) to illustrate the model-based geostatistical methodology introduced in the paper. discussed in the paper. The radionuclide concentration data set consists of measurements of \(\gamma\)-ray counts at \(157\) locations.

Usage

data(rongelapUTM)

Format

A SpatialPolygonsDataFrame, with columns count being the radiation count and time being the length of time the measurement was taken for. A UTM coordinate reference system is used, where coordinates are in metres.
