Description

This function create a plot of electivity values calculated by the function Electivity.

Usage

PlotElectivity(
  Electivity.Calcs,
  Indices = c("Ivlev", "Strauss", "JacobsD", "VanderploegScavia"),
  BarColor = NULL,
  NameSize = 1,
  AxisFontSize = 1,
  BorderCol = "Black",
  LegendFontSize = 1,
  LegendTitle = "Record"
)

Value

One or more plots. Length of the plots will equal the length of the Index parameter

Arguments

Electivity.Calcs

An object of class Electivity produced by the function Electivity.

Indices

Character. Which index should be plotted. Options can include any single index or combination of Ivlev, Strauss, JacobsD, and VanderploegScavia.

BarColor

Character vector. Color to be assigned for each record in Electivity.Calcs. If specified, it should be the sames as the number of rows/records in Electivity.Calcs. If not specified, colors are randomly selected from the rainbow color palette.

Examples

#Load Electivity Data from Horn 1982
data(Horn1982)
#Run all electivity indices
my.indices <- Electivity(Diet = Horn1982$Consumed, Available = Horn1982$Available, 
Indices = c("Ivlev","Strauss","JacobsD","VanderploegScavia"),LogQ = TRUE, Depleting = FALSE)

#Plot All Indices with default colors
PlotElectivity(Electivity.Calcs = my.indices)
#Plot only VanderploegScavia and set colors. Note, there are four records, so we need 
#to set four colors
PlotElectivity(Electivity.Calcs = my.indices, Indices = "VanderploegScavia", 
BarColor = c("Red","Purple","Black","Grey"))
