Excursion Sets and Contour Credibility Regions for Random Fields

Functions that compute probabilistic excursion sets, contour credibility regions, contour avoiding regions, and simultaneous confidence bands for latent Gaussian random processes and fields. The package also contains functions that calculate these quantities for models estimated with the INLA package. The main references for excursions are Bolin and Lindgren (2015) , Bolin and Lindgren (2017) , and Bolin and Lindgren (2018) . These can be generated by the citation function in R.


Excursions is an R package that contains functions that compute probabilistic excursion sets, contour credibility regions, and simultaneous confidence bands for latent Gaussian random processes and fields.

The theory of the methods used in the package are described in Bolin and Lindgren (2014). A manual for the package can be found here and the code used in the manual can be downloaded here.

Versions

The current stable version of the package is 1.1, which is also on CRAN. The development version of the package contains new features and fixes that are not on CRAN. To install this version, see the instructions below.

Installation instructions

The stable version of the package can be installed directly from CRAN, or by using the command

#!r
 
devtools::install_bitbucket("excursions","davidbolin",ref="default")

in R. The development version can be installed using the command

#!r
 
devtools::install_bitbucket("excursions","davidbolin",ref="devel")

The development version of the package is called excursionsdevel, so it is loaded by running

#!r
library(excursionsdevel)

If you want to install the package using the install_bitbucket-method on Windows, you first need to install Rtools and add the paths to Rtools and gcc to the Windows PATH environment variable. This can be done for the current R session only using the commands

#!r
rtools = "C:\\Rtools\\bin"
gcc = "C:\\Rtools\\gcc-4.6.3\\bin"
Sys.setenv(PATH=paste(c(gcc,rtools, Sys.getenv("PATH")),collapse=";"))

where the variables rtools and gcc need to be changed if Rtools is not installed directly on C:.
