fun_report_mig_mult: Calculate daily migration by simple repartition

fun_report_mig_mult R Documentation
Calculate daily migration by simple repartition
Description
Function to calculate daily migration from migration monitoring whose length is less than one day,
typically video recording whose period are instant events.
Usage
fun_report_mig_mult(time.sequence, datasub, negative = FALSE)
Arguments
time.sequence
the time sequence to be filled in with new data
datasub
the initial dataset
negative
'boolean', default FALSE, TRUE indicates a separate sum for negative and positive migrations
Value
A data.frame with number summed over over the time.sequence.
The function returns the same output than fun_report_mig_mult_overlaps
but is intended to work faster. In the data.frame, the total number is
'Effectif_total' and corresponds to the addition of numbers and numbers converted from weight,
the total weight is 'Poids_total'+'poids_depuis_effectifs' and corresponds to weighed glass eel plus glass eel number converted in weights.
