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.
Thanks.
Howard

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' is being vague, the 'specified modules' are the
DLLs from
graphviz.
Have you checked that your 'PATH' environment variable is set
correctly?
In R
> strsplit(Sys.getenv("PATH"), ";")
$PATH
...
[14] "C:\\Program Files\\Graphviz2.20\\bin"
...
The relevant files in this directory might look like
list.files(strsplit(Sys.getenv("PATH"), ";")[[1]][[14]], "dll")

Thank you.

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.

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.
Duncan Murdoch
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
