summary.traps {secr}R Documentation

Summarise Detector Array

Description

Concise description of traps object.

Usage

## S3 method for class 'traps':
summary(object, getspacing = TRUE, ...)
## S3 method for class '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

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.

Value

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

detector detector type ('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
