Hi Martin,
It is really a 'PATH' problem. After adding C:\Program
Files\Graphviz2.20\bin to the 'PATH' environment variable, the
Rgraphviz package can be loaded without any error messages.
Sorry that I ONLY set my 'PATH' environment variable correctly
for R but not for Graphviz.
Thank you and Duncan so much for your great help.

Hi Martin,
I am 100% sure that I set my 'PATH' environment variable
correctly
because all other packages can loaded correctly as well as
because R can
be run correctly under both MS DOS and MS Windows XP. Also, I
can create
some simple R packages correctly.
The PATH must be set correctly to include graphviz, as in my
example
below. Copy and paste the output of
strsplit(Sys.getenv("PATH"), ";")
and
list.files(strsplit(Sys.getenv("PATH"), ";")[[1]][[14]], "dll")
Martin
Thanks.

Hi Martin,
I uninstalled graphviz-2.26.3.msi and then installed
graphviz-2.20.3.1.msi. Then installed the
Rgraphviz package again. As expected, I got the same error
messages as
before:
"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."
'LoadLibrary' is being vague, the 'specified modules' are the
DLLs from
graphviz.
Have you checked that your 'PATH' environment variable is set
correctly?
In R

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)
This is a bioconductor package so please ask on the Bioconductor
mailing
list
http://bioconductor.org/docs/mailList.html
See the 'README' file in the 'tar.gz' file at
http://bioconductor.org/packages/release/Software.html
http://bioconductor.org/packages/2.5/bioc/html/Rgraphviz.html
http://bioconductor.org/packages/2.5/bioc/src/contrib/Rgraphviz_1.24.0.tar.gz
which says
o. install Graphviz ***2.20.3.1*** Windows ***binary***
distribution
from
http://www.graphviz.org/pub/graphviz/stable/windows/graphviz-2.20.3.1.msi
you must use this version of graphviz. File paths must be
correct.
Martin
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

Hi All,
I tried to install the package of Rgraphviz in the
following two
ways successfully:
source("http://bioconductor.org/biocLite.R";)
biocLite("Rgraphviz")
install.packages(pkgs="C:/Progra~1/R/lib_download/Rgraphviz_1.24.0.zip",
lib="C:/Progra~1/R/R-2.10.1/library", repos=NULL)
but when I loaded the package though library(Rgraphviz) or
library("Rgraphviz"), and got the same error message below:
"Error in inDL(x, as.logical(local), as.logical(now), ...) :

Most likely the problem is that you haven't followed the
installation
instructions. (They are pretty hard to find, but I think you can
find
them on the Bioconductor site.) It is not enough to install the
Rgraphviz package, you also need to install Graphviz.

I think that it is the error in the package 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'
Could anyone help me to solve to problem?
Thank you very much for the help. Howard
