# gfcanalysis

## Overview
The `gfcanalysis` package facilitates analyses of forest change using the 
[Global Forest 
Change](http://earthenginepartners.appspot.com/science-2013-global-forest) 
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](http://www.teamnetwork.org).

## Package Installation

## Release Version

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

```R
install.packages('gfcanalysis')
```

## Development Version

The easiest way to install the development version of the `gfcanalysis` package 
is using the 
[`devtools`](https://CRAN.R-project.org/package=devtools)
package. After installing `devtools`, type:

```R
install_github('azvoleff/gfcanalysis')
```

## Usage

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

- For those new to R, see the 
[install_gfcanalysis.R](https://raw.githubusercontent.com/azvoleff/gfcanalysis/master/inst/examples/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](https://raw.githubusercontent.com/azvoleff/gfcanalysis/master/inst/examples/analyze_GFC.R).
