The scripts are all written in R and should work on all platforms, provided that you have the right setup.
Go to the R download site and download R for your system.
-
Mac OS X users, you should get the
R-**.pkgas well astcltk-**.pkgin thetoolssubdirectory further down the page. Installing is just a matter of double-clicking and sayingOKto everything. -
Windows users, you should select the
basesubdirectory and then the mainDownload R ** for Windowslink. Install with the default choices everywhere. -
Linux users, you should get it from your package management system rather than from the above site. The package is usually called R-cran.
We recommend using a specialized editor on top of R, which will become your only interface to R. Download and install RStudio; on the download page, select RStudio Desktop and it should detect your operating system and present the appropriate file for you on the next page.
These scripts are rapidly evolving (at times...) and the latest version is always kept on this page (https://github.com/jiho/atlasr). You can download a zip file using the ZIP button or directly at the address:
https://github.com/jiho/atlasr/zipball/master
Unzipping the file should create an atlasr directory with all the scripts.
Double-click the atlasr.Rproj project file inside the atlasr directory. This will start RStudio and load R in the appropriate location. Load all functions and update the environemental data repository by typing the following command in the "Console" section:
source("initialize.R")
The first time you do this, it will be quite long (over an hour) because it will download all necessary R packages and all environment data layers (well over a Gb of data). In R's console type the command you want to run. These are for example:
do.bioreg()
do.brt()
do.gdm()
For some analyses, documentation is provided in the documentation directory.
