[[Category:Task]]
= Overview =
GLEON and CIDA (center for data analytics) at the USGS have developed two software packages written in the R statistical language to interact with GLM
*GLM: lake model
*GLMr: package designed to support scripted interactions with [[GLM_Software]]. 
*glmtools: tools to reproducible model results, adjust parameter files, and plot visualizations

== Why R? ==
*Performace: stable, light and fast
*Support network 
**documentation, community, developers
*Reproducibility
**anyone anywhere can reproduce results
**enables dissemination - this presentation is a .Rmd file!
*Versatility: unified solution to almost any numerical problem, graphical capabilities
*Testing: integrated “R package” testing limits bugs

== Package Downloads ==
Download R packages from GRAN (Geological Survey R Archive Network) 
*[http://owi.usgs.gov/R/gran.html GRAN]

== glmtools Functions (as of v0.2.5.2) ==
