summary.traps: Summarise Detector Array

Description

Concise description of traps object.

Usage

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

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.
