summary.traps {secr}

R Documentation

Summarise Detector Array

Description

Concise description of traps object.

Usage

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

Arguments

object	traps object
getspacing	logical to calculate spacing of detectors from scratch
covariates	logical; if true each covariate is summarised
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 ("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
