Hi,
I have problem loading Rgraphviz. Following the instructions specified by the
README in Rgraphviz_1.20.3.tar.gz didn't help either.
o. set the following Windows environment variables accordingly
(control panel -> systems -> Advanced -> Environment Variables ):
(a) create new user variables:
GRAPHVIZ_INSTALL_DIR (e.g., C:\Graphviz-2.21)
<-------------------------- I stated C:\Graphviz-2.21 (I also tried
C:\/Graphviz-2.21)
GRAPHVIZ_INSTALL_MAJOR (e.g., 2)
<-------------------------- I stated 2
GRAPHVIZ_INSTALL_MINOR (e.g., 20)
<-------------------------- I stated 21
Notice the way "\/" are used for the paths above.
(b) add to user variable 'path': $GRAPHVIZ_INSTALL_DIR/bin
e.g., C:\Graphviz-2.21\bin
<-------------------------- I stated C:\Graphviz-2.21\bin (I also tried
C:\/Graphviz-2.21\/bin)
> library("Rgraphviz")

Rgraphviz is a Bioconductor package, so please ask on the apporpriate mailing list (see the posting guide). On Tue, 2 Dec 2008, Daren Tan wrote:> > Hi, > > I have problem loading Rgraphviz.

You did actually install graphviz, I presume?> In addition: Warning messages: > 1: closing unused connection 4 (D:/PROGRA~1/R/R-28~1.0/library/Rgraphviz/libs/Rgraphviz.dll) > 2: closing unused connection 3 (D:/PROGRA~1/R/R-2.8.0/library/Rgraphviz/libs/Rgraphviz.dll) > Error : .onLoad failed in 'loadNamespace' for 'Rgraphviz' > Error: package/namespace load failed for 'Rgraphviz' > >> file.exists("D:/PROGRA~1/R/R-28~1.0/library/Rgraphviz/libs/Rgraphviz.dll") > [1] TRUE > >> sessionInfo() > R version 2.8.0 (2008-10-20) > i386-pc-mingw32 > locale: > LC_COLLATE=English_United States.1252;LC_CTYPE=English_United States.1252;LC_MONETARY=English_United States.1252;LC_NUMERIC=C;LC_TIME=English_United States.1252 > attached base packages: > [1] grid stats graphics grDevices utils datasets methods base > other attached packages: > [1] graph_1.20.0 > loaded via a namespace (and not attached): > [1] cluster_1.11.11 tools_2.8.0 > > ______________________________________________ > R-help at r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. >-- Brian D.

You can get LoadLibrary failures if a dependency is not found (e.g. a required
dll or shlib used by the dll that you are explicitly loading). So make sure that
all necessary dependencies (e.g. graphviz libs) are available in the system
path.
