Dear all, I have problems loading the Rgraphviz package under Windows with the newest version of R. The Windows I am using is Windows XP Professional (Version 2002) Service Pack 2. Here is the error message I am getting: Error in inDL(x, as.logical(local), as.logical(now), ...) : unable to load shared library 'C:/PROGRA~1/R/R-27~1.0RC/library/Rgraphviz/libs/Rgraphviz.dll': LoadLibrary failure: The specified module could not be found. Error : .onLoad failed in 'loadNamespace' for 'Rgraphviz' Error: package/namespace load failed for 'Rgraphviz' The version of Bioconductor is 2.2. And here is the session info: R version 2.7.0 RC (2008-04-16 r45356) 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] SparseM_0.77 graph_1.17.17 loaded via a namespace (and not attached): [1] cluster_1.11.10 tools_2.7.0 Thanks a lot. Best, Jasmina

Rgraphviz in R 2.7 / Bioc 2.2 has additional system requirements. There is a Readme file available in the SOURCE distributions of Rgraphviz, e.g., http://bioconductor.org/packages/2.2/bioc/html/Rgraphviz.html and then clicking on the 'Rgraphviz_1.17.14.tar.gz' (NOT windows .zip, the README file is in a location that means it is not included in the Windows binary file; this will be corrected). Basically, you'll need to install graphviz on your computer, and then create enviornment variables that point to the location where graphviz was installed. You'll then be able to use biocLite to install Rgraphviz. Please let me konw (on or off list) how this goes.

Hello, Jasmina. Did you use biocLite to install it? If not, try uninstalling it, use biocLite to install, and see if that fixes the problem. > And here is the session info: > R version 2.7.0 RC (2008-04-16 r45356) > 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] SparseM_0.77 graph_1.17.17 > > loaded via a namespace (and not attached): > [1] cluster_1.11.10 tools_2.7.0 > > Thanks a lot. > > Best, > Jasmina > > _______________________________________________ > Bioconductor mailing list > Bioconductor at stat.math.ethz.ch > https://stat.ethz.ch/mailman/listinfo/bioconductor > Search the archives: http://news.gmane.org/gmane.science.biology.informatics.conductor >
