secr (version 1.5.1)

detector: Detector Type

Description

Extract or replace the detector type.

Usage

detector(object, ...)
detector(object) <- value

Arguments

object

object with `detector' attribute e.g. traps

value

character string for detector type

...

other arguments (not used)

Value

• character string for detector type

Details

Valid detector types in secr 1.5 are `single', `multi', `proximity', `count', `signal', `polygon', and `transect' (the last two are poorly undocumented in 1.5). The detector type is stored as an attribute of a traps object. Detector types are mostly described by Efford et al. (2009a,b). The `signal' detector type is used for acoustic data as described in the documentation file `secr-sound.pdf' (e.g., RShowDoc(package='secr', 'secr-sound')). See also `secr-overview.pdf'.
