Yes I did. Before installing the Rgraphviz package successfully,
(1) I downloaded graphviz-2.26.3.msi for MS Windows (XP) and
installed it successfully and (2) I also installed the packages
from Bioconductor by: (Note: I use MS Windows XP and R 2.10.1
version)
From the instructions:
The right version of Graphviz for Bioconductor 2.5 is version
2.20.3.1.

source("http://www.bioconductor.org/biocLite.R";)
biocLite()
I got those error messages:
"Error in inDL(x, as.logical(local), as.logical(now), ...) :
unable to load shared library
'C:/PROGRA~1/R/R-210~1.1/library/Rgraphviz/libs/Rgraphviz.dll':
LoadLibrary failure: The specified module could not be
found."
Obviously, it seems it is the package problem because it should
go to
'C:/PROGRA~1/R/R-2.10.1/library/Rgraphviz/libs/Rgraphviz.dll'
instead of
'C:/PROGRA~1/R/R-210~1.1/library/Rgraphviz/libs/Rgraphviz.dll'
Thank you for the reply. Howard
