[R] PCALG Package

[Paul Johnson]

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 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.
