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
90th percentile of humid
temp
Average temperature: 1961-1990
temp90
90th percentile of temp
h10pix
maximum of texttt{humid}, within a 10 pixel radius
h10pix90
maximum of texttt{humid90}, within a 10 pixel radius
trees
Percent tree cover, from satellite data
trees90
90th percentile of texttt{trees}
NoYes
Was dengue observed? (1=yes)
Xmin
minimum longitude
Xmax
maximum longitude
Ymin
minimum latitude
Ymax
maximum latitude

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.
