The gfcanalysis package facilitates analyses of forest change using the Global Forest Change dataset released by Hansen et al. 2013, and subsequent versions of that data. The package was originally designed to support the work of the Tropical Ecology Assessment & Monitoring (TEAM) Network.

To install the release version of gfcanalysis in R, just run:

install.packages('gfcanalysis')

The easiest way to install the development version of the gfcanalysis package is using the devtools package. After installing devtools, type:

library(devtools)
install_github('yfinegold/gfcanalysis')

There are two example scripts demonstrating how to use the gfcanalysis package:

• For those new to R, see the install_gfcanalysis.R script. This script provides guidance on how to download and install the (development version) of the package in R.

• For an example of how to run the package to calculate forest change statistics for a given area of interest (AOI), see the examples in analyze_gfc.R.
