wffc.points: Point System for the 2008 World Fly Fishing Championships

Description

Point system for the 2008 World Fly Fishing Championships: current and proposed.

Usage

wffc.P1(length, min.eligible = 0.18)
wffc.P1star(length, min.eligible = 0.18)
wffc.P2(length, min.eligible = 0.18)
wffc.P2star(length, min.eligible = 0.18)

Arguments

length

Length of the fish, in metres. Numeric vector.

min.eligible

Currently the regulations stipulate that the smallest eligible fish is 180 mm.

Value

• A vector with the number of points.

Details

The official website contains a document with the official rules and regulations of the competition. The function wffc.P1() implements the current WFFC point system. wffc.P1star() is a `continuous' version of it.

The function wffc.P2() is a new proposal which rewards catching bigger fish. wffc.P2star() is a `continuous' version of it.
