R help - Jan 2009 - PCALG Package

Hi all,

Can anyone help me setup  this package so I can use it.  I am getting errors
with the Rgraphviz package and have tried a number of ways to get this to work. 
Any help will be greatly appreciated!  I am sorta new to R but have been
actively trying to get into using it as my main analysis software.

Thanks,

Brock

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.

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.
