focal.profPlot {ordiBreadth}

focal.profPlot

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
