Sighting Attributes
Extract or replace the markocc attribute of a traps
object that distinguishes marking occasions from sighting
occasions. Also, extract or replace the attributes Tu, Tm and Tn of a capthist
object, used for storing counts of sightings. All attributes are
optional, but Tu, Tm and Tn require markocc to be specified.
markocc(object, ...) markocc(object) <- value sighting(object) Tu(object, ...) Tu(object) <- value Tm(object, ...) Tm(object) <- value Tn(object, ...) Tn(object) <- value

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 Tu, Tm or Tn, ‘value’ may be a scalar
(total count) or a detectors x occasions matrix.
markocc(object) returns the markocc vector of the traps
object. markocc(object) may be NULL.
Tu, Tm and 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.
