arguments passed to other functions

CHlist

capthist object, especially a multi-session object

counts

character vector of count names

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

Details

These counts are reported by summary.capthist ll{ 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 `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.
