other arguments (not used)
For replacement of markocc, ‘value’ should be a vector of integers indicating the occasions on which animals are sighted only (0) or marked or recaptured (1).
For replacement of
Tn, ‘value’ may be a scalar
(total count) or a detectors x occasions matrix.
markocc(object) returns the markocc vector of the
markocc(object) may be NULL.
Tn return the respective attributes of a capthist object, or
NULL if they are unspecified.
sighting(object) returns TRUE if the markocc attribute indicates at least one sighting-only occasion.
