summary.pars.survey.pt: Default Summary for Point Transect Survey Parameters

Description Usage Arguments Details See Also Examples

Description

This function summarises the content of a 'pars.survey.pt´ object and produces plots of the survey region and detection function.

Usage

1
      summary(pars, digits=5, plot=FALSE)

Arguments

pars

object of class 'pars.survey.pt´.

digits

The number of significant figures numbers are rounded to

plot

if TRUE, a plot is produced of the detection functions for minimum and maximum exposures

Details

This function is useful for viewing the detection function specified in a ‘pars.survey.lt’ object; the detection functions for the least detectable animals (those with minimum exposure) and for the most detectable animals (those with maximum exposure) are plotted.

The detection function form and its parameter values are printed.
