capthist.parts: Dissect Spatial Capture History Object
Description
Extract parts of an object of class 'capthist'.
Usage
animalID(object, names = TRUE)
occasion(object)
trap(object, names = TRUE)
xy(object)
signal(object)
xy(object) <- value
signal(object) <- value
Arguments
object
a 'capthist' object
names
if FALSE the values returned are numeric indices rather than names
value
replacement value (see Details)
Value
For animalID and trap a vector of numeric or character values, one per detection.
For occasion, a vector of numeric values, one per detection.
For xy, a dataframe with one row per detection and columns 'x' and 'y'.For signal, a numeric vector with one element per detection.
Details
These functions extract data on detections, ignoring occasions when an
animal was not detected.
trap returns polygon or transect numbers if traps(object)
has detector type 'polygon' or 'transect'.
Replacement values must precisely match object in number of
detections in their order. xy<- expects a dataframe of x and y
coordinates for points of detection within a 'polygon' or 'transect'
detector.
