[R] "Spreading risk" in a matrix

I have a binary matrix that represents a map of invasive species risk (1 = infested; 0 = uninfested). It started as a matrix of probabilities (developed in ArcMap) that I converted to binary with this R code: binary.matrix<-matrix(rbinom(length(prob.matrix),prob=prob.matrix,size=1),nrow=nrow(prob.
