The official release of the package is on CRAN: http://cran.r-project.org/web/packages/phia/
To get it installed, just write in an R session:
install.packages("phia", repos="http://cran.r-project.org")To work with the newest development version, check the build status icon at the top of this page. If it says “passing”, you should be able to install it from the source. Clone this Git repository in your machine, and if you have the tools to build R packages, do it and install it as appropriate for your OS.
If you cannot build it, you may still install it from an R session. Set the working directory to the parent folder where phia is copied, and then do:
install.packages("phia", repos=NULL, type="source")In this case, the package dependencies and the PDF docs will not be installed. You should at least install package car (from CRAN) separately to have a fully operative package.
After installing, you have to load to use the package, with:
library(phia)For further details about how to use the package, read the vignette that comes with it.
