Note that POSAC works best as a small data technique. In particular, if you have a very large number of variables don't be surprised if analysis fails to produce useful results.
In order to run all of the examples in this package you will first need to install the packages ggplot2 and hasseDiagram from CRAN, and the package Rgrpahviz from Bioconductor. This can be done with the commands below.
source("https://bioconductor.org/biocLite.R")
biocLite("Rgraphviz")
install.packages("ggplot2","hasseDiagram","foreach")
This package can then be installed using the devtools package using the commands below.
library(devtools)
install_github("CambridgeAssessmentResearch/POSAC")
