plotOrnithoPheno: Plot Phenology of Bird Observations

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

Description

Plots phenology of bird observations based on count maxima per sites and number of observations

Usage

plotOrnithoPheno(x, unit = "decade", from = "Jan", 
    to = "Dec", col)

Arguments

x	an object of class ornithoSpec.
unit	a time unit in which to devide the plot, either "decade" or "pentade", the default is "decade".
from, to	a character string giving one of "Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", or "Dec" (see Details).

col	a nine-level color palette, the third and sixth levels are used to plot, respectively. The default are grey levels returned by gray.

Details

Arguments from and to can be used to subset or shift the order of months in the plot. To display only the breeding season of a set of species one could choose from = "Mar" and to = "Jun". For wintering birds it might be useful to shift the plot by six months: from = "Jul" and "Jun".
