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
