MakeAnglers: Create a population of anglers

In stevenranney/creelSurvey: Simulate a Bus Route Creel Survey of Anglers

Description

Creates a population of nanglers with trip length and fishing day length provided by the user.

Usage

MakeAnglers(nanglers = 100, meanTripLength = 3.88, fishingDayLength = 12)

Arguments

nanglers	The number of anglers in the population
meanTripLength	The mean trip length to be used in the function. 3.88 is the default. The default is from data from the 2008 Lake Roosevelt Fishing Evaluation Program.
fishingDayLength	The fishing day length to be used in the function. Anglers are not be allowed to be fishing past this day length. The default here is set to 12 hours, which may not be a suitable day length for fisheries at higher latitudes (i.e., sunrise-sunset is > 12 hours) or during shorter seasons.

Details

All trip lengths will be limited so that anglers have finished their fishing trip by the end of the fishing day. The function uses a while loop to ensure that the number of angles = nanglers provided in the function argument. fishingDayLength is passed to the argument. The default is set to 12 hours. starttimes are assigned by the uniform distribution triplengths are assigned by the gamma distribution where the default mean value comes from the 2008 Lake Roosevelt Fisheries Evaluation Program data.
