Dengue prevalence, by administrative region
Description
Data record, for each of 2000 administrative regions, whether or not dengue was recorded at any time between 1961 and 1990.
Usage
data(dengue)Format
A data frame with 2000 observations on the following 13 variables.
- humid
Average vapour density: 1961-1990
- humid90

Details
This is derived from a data set in which the climate and tree cover
information were given for each half degree of latitude by half
degreee of longitude pixel.
The variable NoYes was given by administrative region.
The climate data and tree cover data given here are 50th or 90th
percentiles, where percetiles were calculates across pixels for an
administrative region.
