In DAAG: Data Analysis and Graphics Data and Functions

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 humid, within a 10 pixel radius

h10pix90

maximum of humid90, within a 10 pixel radius

trees

Percent tree cover, from satellite data

trees90

90th percentile of 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.
