test.idturtle: Test data of known turtles

In IDTurtle: Identify Turtles by their Plastral Biometries

Description

Test some data of known turtles previously processed with turtle.idturtle to detect errors in the identification. For example, if some marking system is bad readed.

Usage

test.idturtle(data.comp, data.ref, date = "date", ID = "ID", PL = "PL")

Arguments

data.comp	Dataframe with data of the last measurements of specimens to test
data.ref	Dataframe with the database of measurements of all the specimens
date	Name of the column with the date in both data.comp and data.ref
ID	Name of the identification code of the turtle column in both data.comp and data.ref
PL	Name of the plastral length column in both data.comp and data.ref

Details

The function also write in the hard disc a csv file named "effectivity.csv", which has the same data than the dataframe generated with this function.

Value

Dataframe with the following columns: ID: The ID of the tested turtle Ident: If all the measurements of the turtle is identified as the first option Years: Number of Years between the first capture and the las recapture of the turtle minPL: The minimum size of PL (usually the size of the first capture) PLDif: The difference in PL size between the first and last capture of the turtle maxRMSD: The maximum value between the tested measurement with any other of the same turtle. Is the worst RMSD value of a measurement of the same turtle with the tested measuremnt minRMSD: The minimum RMSD value of the tested measurement and any other turtle different than the tested one NMeasurements: The number of measurements of other turtles classified better than the worst clasified measurement of the tested turtle NTurtles: The number of turtles with at least one measurement best clasified that the worst measurement of the tested turtle

Note

test.idturtle will not work if you not make previously the analysis with idturtle.idturtle, because test.idturtle must read the auxiliary files created during the idturtle.idturtle analysis

Examples

# Charge example data
data(data.comp, data.ref)
# Reduce target turtles to make faster the example execution
data.comp<-data.comp[1:3,]
data.ref<-data.ref[order(data.ref[,c("ID")]),]
data.ref<-data.ref[1:200,]
# Note that date column in our data is named in Spanish (Fecha)
identity<-turtle.idturtle(data.comp,data.ref,date="Fecha")
# Execute the test
test<-test.idturtle(data.comp,data.ref, date="Fecha")
