spsurvey

spsurvey is comprised of functions which implement algorithms for design and analysis of probability surveys. The functions are tailored for Generalized Random Tessellation Stratified survey designs.

Installation

You can install the released version from CRAN using:

# install from CRAN
install.packages('spsurvey')
library(spsurvey)

You can install development version ofspsurvey from GitHub with the following:

# requires devtools to install

library(spsurvey)

Example

An overview of the spsurvey package is provided in the users guide that is included with the package. The documentation includes a number of vignettes for the design and analysis of survey designs for point (finite), linear and area (polygons) spatial features. Vignettes are also available for typical survey analyses.
