Diagnostics for the detectability with respect to Julian Date

Source: R/plot_DetectionPhenology.R
plot_DetectionPhenology.Rd

Creates a plot of detectability over the season and calculates some simple statistics

Usage

plot_DetectionPhenology(
  model,
  spname = NULL,
  bins = 12,
  density_function = TRUE
)

Arguments

model

a fitted sparta model of class OccDet.

spname

optional name of the species (used for plotting)

bins

number of points to estimate across the year. Defaults to 12

density_function

whether the model used a density function to fit Julian date. This form was implemented from version 0.1.48 onwards. For models ran using earlier versions of the package this should be set to FALSE

Value

This function returns plot showing the detection probability on the y axis and Julian day on the x. The data within the output list shows the Julian day for each point estimated (equal to the number of bins) and the mean detection probability with 95

Details

Takes a object of OccDet fitted with the jul_date option

Calculates the phenology of detection and produces a plot of detectability over time for the reference data type.
