movementSpeeds

Triggers movementTimes and also calculates the speed between events.

Designed for studies where animals tagged with acoustic tags are expected
to move through receiver arrays. This package combines the advantages of automatic sorting and checking
of animal 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>.

movementSpeeds function

<dl><dt>movements</dt>
<dd>the movement dataframe for the tag being analysed.</dd>
<dt>speed.method</dt>
<dd>Can take two forms: 'last to first' or 'last to last'.
If 'last to first' (default), the last detection on the previous array is matched
to the first detection on the target array to perform the calculations.
If 'last to last', the last detection on ´the previous array is matched to the
last detection on the target array to perform the calculations.</dd>
<dt>dist.mat</dt>
<dd>A matrix of the distances between the deployed ALS.</dd></dl>
