PCALG Package
This means you need to install the Rgraphviz package. Have you tried? For me, Rgraphviz is not in CRAN, but it is required for that package you want. Rgraphviz is hosted in biocondoctor, so you have to install it through that route. http://www.bioconductor.org/packages/release/bioc/html/Rgraphviz.html After that, you re-install the other package you really wanted.

I can not even get the package to run. I installed the package, and it is telling me I need rGraphViz. I was told to install it was included in the Bioconductor package, but that did not work either. The error message I routinely get is surrounding a "missing" RGraphViz package. I have searched the internet, saw a place to install it. I attempted that as well, but to no avail. I am stumped. Does it work for you? IF so, when did you install the package? Many thanks, Brock
