initvals: Generate initial status for nodes

In GarrettLab/INApreliminary: Impact Network Analysis

Description

This function generates the initial status for nodes, in terms of the presence of management information or focal species

Usage

initvals(geocoords4s, dist4, init.p4, init.n4, norp4, plotmp = F)

Arguments

geocoords4s	n by 2 matrix of geographic coordinates, provided for a particular system or generated by function genlocs
dist4	the type of locations where initial presence occurs: 'random' indicates all equally likely, 'upedge' indicates that nodes closest to the upper edge have presence, 'rightedge' indicates that nodes closest to the right edge have presence
init.p4	the proportion of initial locations for presence
init.n4	the number of initial locations for presence
norp4	'num' indicates initial number for presence, 'prop' indicates initial proportion
plotmp	if T, then map of presence and absence is plotted

Examples

x2 <- initvals(j2 <- genlocs(xrange4=c(0,50), yrange4=c(0,50), numnodes4=100, randgeo4=TRUE),dist4='random', init.p4=0.1, norp4='prop', plotmp=T)
x3 <- initvals(j2 <- genlocs(xrange4=c(0,50), yrange4=c(0,50), numnodes4=100, randgeo4=TRUE),dist4='upedge', init.p4=0.3, norp4='prop', plotmp=T)
x4 <- initvals(j2 <- genlocs(xrange4=c(0,50), yrange4=c(0,50), numnodes4=100, randgeo4=TRUE), dist4='rightedge', init.p4=0.3, norp4='prop',plotmp=T)
x5 <- initvals(geocoords4s=matrix(c(1,5, 2,5, 3,5, 4,5), byrow=T, ncol=2), dist4='upedge', norp4='num', init.n4=2, plotmp=T) 
x6 <- initvals(geocoords4s=matrix(c(5,1, 5,2, 5,3, 5,4), byrow=T, ncol=2), dist4='rightedge', norp4='num', init.n4=2, plotmp=T)
