character string for detector type
Valid detector types are `single', `multi', `proximity', `count', `capped',
`signal', `polygon', `transect', `polygonX', and `transectX'. The
detector type is stored as an attribute of a traps object.
Detector types are mostly described by Efford et al. (2009a,b; see also
secr-overview.pdf). Polygon and transect detector types are
for area and linear searches as described in
secr-polygondetectors.pdf and Efford (2011). The `signal'
detector type is used for acoustic data as described in
secr-sound.pdf.
The `capped' detector type refers to binary proximity data in which no more than one individual may be detected at a detector on any occasion. The type is partially implemented in secr 3.1.1: data may be simulated and manipulated, but for model fitting these are treated as proximity data by secr.fit().
