summary.traps: Summarise Detector Array

Description

Concise description of traps object.

Usage

# S3 method for traps
summary(object, getspacing = TRUE, …)
# S3 method for summary.traps
print(x, terse = FALSE, …)

Arguments

object

traps object

getspacing

logical to calculate spacing of detectors from scratch

x

summary.traps object

terse

if TRUE suppress printing of usage and covariate summary

…

arguments passed to other functions

Value

An object of class summary.traps, a list with elements

detector

detector type ("single", "multi", "proximity" etc.)

ndetector

number of detectors

xrange

range of x coordinates

yrange

range of y coordinates

spacing

mean distance from each trap to nearest other trap

usage

table of usage by occasion

covar

summary of covariates

Details

When object includes both categorical (factor) covariates and usage, usage is tabulated for each level of the covariates.

Computation of spacing (mean distance to nearest trap) is slow and may hit a memory limit when there are many traps. In this case, turn off the computation with getspacing = FALSE.
