plotOrnithoAltitude: Histograms of Altitudinal Distribution

In heibl/rornitho: Functions for Visualisation of Ornitho Bird Observations

Description

Plots histograms of the altitudinal distribution of bird observations from ornitho monitoring data.

Usage

plotOrnithoAltitude(x, background,
  alt.int = 50, alt.min = 0, alt.max = 1000, 
  col = "grey75")

Arguments

x	an object of class ornithoSpec.
background	numeric, a vector of integers that are representative for the distribution of the altitude of the samples. Used to compare the altitudinal distribution of a species samples to the altitudinal distribution sampled.
alt.int	numeric, giving an interval (in meters) for summarizing observations.
alt.min	numeric, giving the minimal altitude (in meters) for scaling the altitude histogram.
alt.max	numeric, givint the maximal altitude (in meters) for scaling the altitude histogram.
col	any valid specification of a color to fill the bars of the plot.
