Details

Valid detector types in version 1.4 are 'single', 'multi', 'proximity', 'count', 'signal', 'quadratbinary', 'quadratcount', 'polygon', and 'transect' (the last four are undocumented in 1.4.0). 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 the documentation files 'secr-overview' and 'secr-sound'.
