varcomp: Variance Components for glmssn Objects

Description

The varcomp function displays the variance proportions for the autocovariance functions in the glmssn object.

Usage

varcomp(object)

Arguments

object

a glmssn-class object

Value

A data frame with two columns. The first column is the name of the variance component and the second column is the proportion for each variance component.

Details

The varcomp function displays the variance component for each autocovariance function, as well as the Covariates component and the nugget.

Examples

Run this code


	library(SSN)
	# NOT RUN 
	#mf04p <- importSSN(system.file("lsndata/MiddleFork04.ssn", 
	#  package = "SSN"), predpts = "pred1km", o.write = TRUE)
	#  use SpatialStreamNetwork object mf04p that was already created
	data(mf04p)
	#make sure mf04p has the correct path, will vary for each users installation
	mf04p@path <- system.file("lsndata/MiddleFork04.ssn", package = "SSN")
		  
	# get some model fits stored as data objects
	data(modelFits)
	#NOT RUN use this one
	#fitSp <- glmssn(Summer_mn ~ ELEV_DEM + netID,
	#    ssn.object = mf04p, EstMeth = "REML", family = "Gaussian",
	#    CorModels = c("Exponential.tailup","Exponential.taildown",
	#    "Exponential.Euclid"), addfunccol = "afvArea")
	#make sure fitSP has the correct path, will vary for each users installation
	fitSp$ssn@path <- system.file("lsndata/MiddleFork04.ssn", package = "SSN")

	varcomp(fitSp)
