PIT tag based trap rate

Description

Estimate the trap rate at Lower Granite by using the proportion of previously PIT tagged fish observed pass a location that were found in the fish trap at that location.

Usage

tagTrapRate(
  trap_dataframe = NULL,
  week_strata = NULL,
  mark_site = c("LGRLDR", "LGR")
)

Arguments

`trap_dataframe`	dataframe containing data from the fish trap, including columns named `Tag.ID`, `CollectionDate` and `SRR`.
`week_strata`	vector of intervals delimiting the weekly strata to summarize mark-recapture data over, as returned by the `weeklyStrata` function.
`mark_site`	PTAGIS code for the site at the location being queried for trap rate. This is used to filter out fish that were marked at the fish trap.
