fun_report_mig_mult_overlaps

Function to calculate daily migration from migration monitoring whose length is more than one day,
this calculation relies on the (false) assumption that migration is evenly spread over time.

Graphical outputs and treatment for a database of fish pass
monitoring. It is a part of the 'STACOMI' open source project developed in
France by the French Office for Biodiversity institute to centralize
data obtained by fish pass monitoring. This version is available in French and
English. See <http://stacomir.r-forge.r-project.org/> for more information on
'STACOMI'.

be converted to 'daily' values assuming that the migration was regular over time. The function
returns one row per taxa, stages, counting device. It does not account for the destination of taxa. It returns
separate rows for quantities and numbers. Several columns are according to the type of measure (MESURE, CALCULE, PONCTUEL or EXPERT).</dd></dl>
