Determine optimal spatial arrangement for direct sampling — sampling_strategy

Function that determines the optimal spatial arrangement for direct sampling sites

Usage

sampling_strategy_direct(river, nSites)

Arguments

river: A river object generated via aggregate_river.
nSites: Number of sites to be deployed. Cannot be higher than river$AG$nNodes.

Value

A vector containing the ID of the nSites selected sites according to this strategy. Sites are sorted according to their rank (i.e., the first site in the vector is the first one that has been selected).

Examples

library(rivnet)
data(wigger)
wigger <- paths_river(wigger) 
sites <- sampling_strategy_direct(wigger, 20)
plot(wigger)
points_colorscale(wigger$AG$X[sites], wigger$AG$Y[sites], 1:20)
