plotbin: Function to plot the distribution of lag distance bin sizes

Description

A convenience function that provides a histogram of distances among of all sample pairs and a plot of sample sizes for each the selected bin size.

Usage

plotbin(dist.mat,binsize)

Arguments

dist.mat

a vector of x-y distances among all sample pairs as produced by calc.dist

binsize

A vector of bin sizes as produced by make.bin, or of the form c(0,2,3,4,....) where the values are the desired bin cutoffs beginning with zero.

Details

This function is to assist in visualization of both the distribution of x-y distances in the dataset and sample sizes resulting from the selected lag distance bins. See the help files for calc.dist and make.bin for the inputs to this function.

Examples

data=plantcomp
distancematrix<-calc.dist(plantcomp[c(1:100),])
#using subset of plantcomp dataset to cut computation time
Plant_bins<-make.bin(distancematrix,type="s.size",s.size=200) 
#inference distance=50% AND sample size=200
binsize<-Plant_bins[1][[1]] #plant competition bin sizes
