secr (version 3.0.1)

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.
