In apear9/SSNdesign: An R Package for Optimal and Adaptive Sampling Designs on Stream Networks

Description

This function transfers specified variables recorded on the edges of a SpatialStreamNetwork object to the observed (and possibly prediction) sites in that SpatialStreamNetwork object.

Usage

extractStreamEdgeCovariates(ssn, columns)

Arguments

ssn	an object of class SpatialStreamNetwork
columns	a vector of column names that should be extracted from the data slot of the SpatialStreamNetwork object

Value

An object of class SpatialStreamNetwork.

Examples

set.seed(1)

# Create an SSN
s <- createSSN(10, binomialDesign(10), 
path = paste(tempdir(), "example01.ssn", sep = "/"), importToR = TRUE)

# Extract stream edge covariates
s <- extractStreamEdgeCovariates(s, "Length")
