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
