focal.profPlot: focal.profPlot

In ordiBreadth: Ordinated Diet Breadth

Description

Plots the profile plot of distance from herbivore centroid to host plants calculated by excluding the focal herbivore. Useful for exploratory data analysis.

Usage

focal.profPlot(dat, focal.bug, dist.method = "jaccard", col = c("black", "red"))

Arguments

dat	A matrix of diet associations. Rows are herbivores and columns are diet items.
focal.bug	A value indicating which herbivore is the focal herbivore.
dist.method	Dissimilarity index passed on to vegdist in the vegan package.
col	A vector length 2 indicating colors for plotting. First color is for non-diet items, second color is for diet items.

Value

A profile plot
