dpcR is available on CRAN, so installation is as simple as:
install.packages("dpcR")
You can install the latest development version of the code using the devtools
R package.
# Install devtools, if you haven't already.
install.packages("devtools")
library(devtools)
install_github("michbur/dpcR")
The dpcReport GUI may be downloaded a standalone application (does not require prior installation of R) from SourceForge.
