In SimVitD: Simulation Tools for Planning Vitamin D Studies

Generate an intensity function

Description

Generates intensity function, function with time as sole argument.

Usage

  intensity.function( summer.rate = 0, winter.rate = 1, flu = TRUE )

Arguments

summer.rate	Value bwteeen 0 and 1, the rate at which exposures occur in summer months.
winter.rate	Value between 0 and 1, the rate at which exposures occur in winter months.
flu	If TRUE define winter months as flu season (Sep-May in Northern Hemisphere, Mar-Nov in Southern Hemisphere). If FALSE have constant exposure rate all year.

Value

intensity.function returns a function that takes time as sole argument and returns value between 0 and 1, the returned function acts as intensity.func for input to exposure.levels.
