PIT tag based trap rate

Description

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

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.
