[BioC] Rgraphviz, R 2.7.0 and Windows XP - SOLVED!

[Jenny Drnevich]

Hi everyone,

I finally got Rgraphviz to work from the Windows binary. For some 
reason, Graphviz versions that didn't seem to work last week are 
working this week! I just tried the following on two "virgin" Windows 
machines, and it seems to work:

1. Download and install Microsoft Visual C++ 2005 SP1 Redistributable 
Package: 
http://www.microsoft.com/downloads/details.aspx?familyid=200B2FD9-AE1A-4A14-984D-389C36F85647&displaylang=en

2. Download and install the current stable release for Windows of 
Graphviz 2.18.1: 
http://www.graphviz.org/pub/graphviz/ARCHIVE/graphviz-2.18.1.exe 
(yes, I know before we were saying 2.16.1 was needed, but for some 
reason 2.18.1 is working this week!)


3. From within R, download and install Rgraphviz using:
 > source("http://bioconductor.org/biocLite.R")
 > biocLite("Rgraphviz")

4. If everything goes well, this should work:
 > library(Rgraphviz)

I'm not having any troubles now, at least in loading the 
package!  Special thanks to Martin Morgan and Tony Chiang for helping 
me sort this out off-list.

Cheers,
Jenny

BTW - there's a known bug in graphviz-2.18.exe that the uninstall.exe 
file doesn't work. Won't matter until you try to uninstall it! They 
said to install the development release to the same folder and start 
menu and then uninstall.
