Description Usage Arguments Examples
Define arguments for hook and line simulations; arguments the same as make_ctl function Used in initialize_population

|
numrow |
Number of rows in matrix |
numcol |
Number of columns in matrix |
nfish |
Number of fish to allocate among matrix |
distribute |
Specify fish distribution to be 'uniform', 'patchy', or 'area' specific |
maxfish |
Maximum number of fish that can be sampled at a time; default is 10 |
percent |
percentage of area to sample. Only necessary if distribute == 'patchy'; default is 0.3 |
area |
Specify area to distribute fish, options are 'upperleft', 'upperright', 'lowerleft', 'lowerright', 'upperhalf', 'lowerhalf', 'righthalf', 'lefthalf' Only necessary if distribute == 'area' |
seed |
Set seed if distribute == random, defaults to 300 |
location |
Data frame of locations with column for vessel, rows, and columns of fish are to fish in. |
scope |
the scope of fishing movement, default to 1 so fish in surrounding 1 cells can move in; default is 1 |
nhooks |
number of hooks at the smallest sampling size; default is 5 |
ndrops |
number of drops, default is 5 following hook and line protocol; default is 5 |
process |
specify process by which fish are sampled, options are 'multinomial', 'hypergeometric', and 'equal_prob'. 'equal_prob' is based on CIE comments from 2012. |
p0 |
Probability that fish detects gear, used in the hook_prob function; default is 0.4 |
nyear |
Number of years in survey; default is 10 |
browser |
Switch to turn on browser for debugging |
cpue_method |
Method of aggregating cpue. For use in calc_cpue function. Currently options are 'average', '75hooks' to aggregate by hooks, and 'weighted_average' is in development |
1 2 | run_sim(nhooks = 15, seed = 200, nfish = 1000, nyear = 15, distribute = 'patchy',
percent = .5, cpue_method = '75hooks')
