rKIN (version 1.0.4)

plotKIN: Plotting function for rKIN polygons

Description

Using ggplot2 methods, simultaneously plot all of the groups and levels of niche space

Usage

plotKIN(
  estObj,
  scaler = 1,
  alpha = 0.3,
  title = "",
  xlab = "x",
  ylab = "y",
  xmin = NULL,
  xmax = NULL,
  ymin = NULL,
  ymax = NULL,
  colors = NULL
)

Value

A plot of all groups and levels.

Arguments

estObj

list object created from estKIN, estMCP or estEllipse functions

scaler

numeric value indicating number of isotopic units to expand the x and y axes of the plot. Default is 1.

alpha

numeric value between 0 and 1, representing the amount of transparency of each polygon. 0 is transparent, 1 is opaque.

title

character string for a plot title.

xlab

character or expression string for the x-axis label.

ylab

character or expression string for the y-axis label.

xmin

default is NULL, numeric value of user specified minimum x axis value

xmax

default is NULL, numeric value of user specified maximum x axis value

ymin

default is NULL, numeric value of user specified minimum y axis value

ymax

default is NULL, numeric value of user specified maximum y axis value

colors

default is NULL, character vector of hex codes representing colors for plot

Examples

library(rKIN)
data("rodents")
#estimate niche overlap between 2 species using kernel UD
test.kin<- estKIN(data=rodents, x="Ave_C", y="Ave_N", group="Species",
                   levels=c(50, 75, 95), scaler=2)
#determine polygon overlap for all polygons
plotKIN(test.kin, scaler = 1, title = "Kernel Estimates",
         xlab = expression({delta}^13*C~ ('Per Mille')),
         ylab = expression({delta}^15*N~ ('Per Mille')))
