Function to calculate Pr(mature|z) for new shell males

Description

Logistic function for Pr(mature|size) for new shell males based on Rugolo and Turnock's fitted logistic curve. Parameters are based on my fit to their curve.

Usage

calc.prMat.Males(z, shell_condition, z50 = 102.32849563, slp = 0.06440451)

Arguments

z	: size (mm CW)
shell_condition	: ‘NEW_SHELL’ or ‘OLD_SHELL’
z50	: size at 50% maturity
slp	: slope for logistic curve (mm^{-1})

Details

Default parameter values are based on my fit to Rugolo and Turnock's fitted logistic curve. Old shell crab are assumed to be terminally-molted, so Pr(mature|z)=1 for all sizes z.

Value

a vector of Pr(mature|z) corresponding to the input sizes and shell condition classification.
