GLM3r

Linux	Windows

R package for basic GLM model running. GLM3r is designed to hold the most current version of the General Lake Model (GLM) for linux, mac, and windows platforms. This package does not contain the source code for the model, only the executable, and functions for handling the various platform requirements for running the model. Also, use glm_version() to figure out what version of GLM you are running.

Installation

You can install GLM3r from Github with:

# install.packages("devtools")
devtools::install_github("GLEON/GLM3r")

Usage

Run

library(GLM3r)

sim_folder <- system.file('extdata', package = 'GLM3r')

run_glm(sim_folder)

Reading config from glm3.nml
No WQ config
No diffuser data, setting default values
