fish

valid.movements

If a fish moves at a speed equal or greater than
<code>speed.warning</code> (in metres per second), a warning is issued. If left
NULL (default), no warnings are issued.

speed.warning

If a fish moves at a speed equal or greater than
<code>speed.error</code> (in metres per second), user intervention is suggested.
If left NULL (default), user intervention is never suggested.

speed.error

One of "needed", "always" or "never". If "needed", a new window is
opened to inspect the movements only if the movements table is too big to be
displayed in R's console. If "always", a graphical interface is always created
when the possibility to invalidate events emerges. If "never", a graphical
interface is never invoked. In this case, if the table to be displayed does
not fit in R's console, a temporary file will be saved and the user will be
prompted to open and examine that file. Defaults to "needed".

check fish speeds against defined thresholds (in m/s)

internal

Designed for studies where fish tagged with acoustic tags are expected
to move through receiver arrays. This package combines the advantages of automatic sorting and checking
of fish movements with the possibility for user intervention on tags that deviate from expected
behaviour. The three analysis functions (explore(), migration() and residency())
allow the users to analyse their data in a systematic way, making it easy to compare results from
different studies.
CJS calculations are based on Perry et al. (2012) <https://www.researchgate.net/publication/256443823_Using_mark-recapture_models_to_estimate_survival_from_telemetry_data>.
