In johnWilshire/contest: Exploration of intra-species contests

Description

Title Runs run_simulation in parallel over parameters Provides a wrapper to perform a line search of a parameter and returns the results of run_simmulation with the parameters specified.

Usage

run_parallel(params, varied_parameter, from, to, by, ...)

Arguments

params	Parameters for 'run_simulation'
varied_parameter
from	Starting value of varied parameter, See 'seq'.
to	Final value of varied parameter. See 'seq'.
by	Increment value. See 'seq'.
mc_opts	Options for mclapply, setting mc.cores is a good idea.

Value

A list of the result of calling run_simulation with the varied parameter.

Examples

 run_parallel(params, "density", 0.1, 4, 0.5, mc.cores = 4) -> sim
 Reduce(rbind, sim) -> df
