Installing required packages

For windows, OSX, or Linux use use the following command in R:

 install.packages("glmtools", 
    repos = c("http://gleon.github.com/", "http://cran.us.r-project.org", "http://usgs-r.github.com/"),
    dependencies = TRUE,
    type = "both")

You now have GLM (GLMr), R tools for GLM (glmtools), NetCDF file handlers (ncdf), and rLakeAnalyzer installed!!

Run GLM demo

library(GLMr)
demo(glm)

If you get a success message, your task is complete!

Troubleshooting

Mac Users: If you get a 'permission denied error' when running demo(glm), you must change the permission setting on the sim folder in terminal.
Example error:

 sh: /Library/Frameworks/R.framework/Versions/3.0/Resources/library/GLMr/extbin/macGLM/bin/glm: Permission denied 

Steps

• Open TERMINAL
• Change directory folder to that listed in the error. (copy bold text, and change to match your personal file path)

example: MyLovley-MacBook-Pro:~ user$ cd /Library/Frameworks/R.framework/Versions/3.0/Resources/library/GLMr/extbin/macGLM/bin

• • If you type ls, you should see 10 files, one of which is titled 'glm'
• Type

 chmod 755 glm 

• You should now be able to run demo(glm)
