Run simulations

The most important functions to setup growR and run simulations.

setup_directory(): Initialize growR directory structure

read_config(): Read simulation run configurations from file

growR_run_loop(): Run growR simulations

Calibration

Routines useful to calibrate model to data.

run_parameter_scan(): Parameter Scan

analyze_parameter_scan(): Analyze results of a parameter scan

plot_parameter_scan(): Plot Parameter Scan Results

parameter_scan_example: Example results of a parameter scan

Analysis

Utilities for analysis of simulated results.

plot(<ModvegeSite>): Plot ModVege simulation result overview

get_bias() root_mean_squared() mean_absolute_error(): Metric Functions
