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, ...)

### Arguments

`object` | `traps` object
`getspacing` | logical to calculate spacing of detectors from scratch
`x` | `summary.traps` object
`...` | 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
