summary.capthist {secr} | R Documentation

## Summarise Detections

### Description

Concise description of `capthist` object.

### Usage

    ## S3 method for class 'capthist':
    summary(object, ...)

    ## S3 method for class 'summary.capthist':
    print(x, ...)

    counts(CHlist, counts = 'M(t+1)')

### Arguments

`object` | `capthist` object
`x` | `summary.capthist` object
`...` | arguments passed to other functions
`CHlist` | capthist object, especially a multi-session object
`counts` | character vector of count names

### Details

These counts are reported by `summary.capthist`

n | number of individuals detected on each occasion
u | number of individuals detected for the first time on each occasion
f | number of individuals detected exactly f times
M(t+1) | cumulative number of individuals detected
losses | number of individuals reported as not released on each occasion
detections | number of detections, including within-occasion 'recaptures'
traps visited | number of detectors at which at least one detection was recorded
traps set | number of detectors, excluding any indicated as not set in `usage` attribute of `traps` attribute

`counts` may be used to return the specified counts in a compact session x occasion table. If more than one count is named then a list is returned with one component for each type of count.

### Value

An object of class `summary.capthist`, a list with at least these components

`detector` | detector type in {'single', 'multi', 'proximity'}
`ndetector` | number of detectors
`xrange` | range of x coordinates of detectors
`yrange` | range of y coordinates of detectors
`spacing` | mean distance from each trap to nearest other trap
`counts` | matrix of summary counts (rows) by occasion (columns). See Details.
`dbar` | mean recapture distance
`RPSV` | root pooled spatial variance
