Usage

GetStuRecap(data, ...)

Arguments

data	Dataframe containing CDFW mark-recapture Sturgeon data.
...	Field names (not quoted) in 'data' where each is named (see details).

Details

Items in '...' must be named accordingly.

type

sturgeon type, i.e. Tagged, Recapture, or Not Tagged; usually found in 'StuType' field in 'Sturgeon' data

shed

field with info on whether the sturgeon shed or possibly shed the disc tag

retag

field with info on whether the sturgeon was retagged

dn

field with original disc tag number

pn

field with original PIT number

od

field with old disc tag number

op

field with old PIT number

Value

List with four items: (1) 'TagNum' - the tag number of the recaptured tag; (2) 'TagType' - describes recapture (i.e., a recapture; a retag; etc.); (3) 'RecordCount' - count of records by tag type & total count; (4) 'Data' - a list with appropriate release & recapture info for each recaptured tag. List is class 'GetStuRecap'.

Note

Admittedly, 'StuType' is a poorly named field & somewhat misleading (e.g., can be confused with species). This field essentially describes the table in which data live in the database (tagged, not tagged, or recaptured). Some tagged fish can be classified as recaptured if the fish had a previous tag and was (thus) retagged. GetStuRecap and other internal functions capture all recaptured fish (including those retagged or those fish with only PIT tags, no disc tags).
