Hi There Jenny I've tried your steps a number of times, but keep getting the same error below! Could you kindly help? Thnx Ernest Loading required package: graph Loading required package: grid Error in inDL(x, as.logical(local), as.logical(now), ...) : unable to load shared library 'C:/PROGRA~1/R/R-29~1.0/library/Rgraphviz/libs/Rgraphviz.dll': LoadLibrary failure: The specified module could not be found.

Hi Ernest, Kasper and others from previous threads of installing Rgraphviz... As noted many times in different threads on this list, there are always problems with Windows users being able to successfully install and use Rgraphviz because of an outside program, Graphviz. I just went through 2 recent threads (links below) after the R 2.9/BioC 2.4 releases, and I still don't have Rgraphviz loading completely without errors (although I think it's functional). First of all, somewhere in one of the threads, Kasper (I think) said he needed to getting around to writing a vignette on how to install everything properly, which would be nice to have in the Documentation section of the Rgraphviz page: http://www.bioconductor.org/packages/release/bioc/html/Rgraphviz.html Instead, the text at the top says to see the README file, which is in the source distribution (probably difficult for the average Windows user to actually get this file!). The instructions in the README file for using the Windows binary of Rgraphviz say to download the Graphviz ***2.22.2*** binary file. However, this is not the correct version, as indicated in the links below. I just tried the Graphviz 2.22.2, and got all the same errors documented before. Then I followed Patrick's suggestion on 4/29/09 to use Graphviz 2.20 available from here: http://www.graphviz.org/pub/graphviz/stable/windows/graphviz-2.20.3.1. msi So here are the step I went through: 1. No other Graphviz version installed on my computer, no C:\Program Files\GraphvizX.XX\bin in my PATH, R not running. 2. Installed Graphviz 2.20 using the file from the link above. 3. Made sure C:\Program Files\Graphviz2.20\bin is in my PATH. 4. Started R, downloaded and installed Rgraphviz using: > source("http://bioconductor.org/biocLite.R") > biocLite("Rgraphviz") Now, according to everything I can find in the archives, this *should* have worked. But when I try: > library(Rgraphviz) I still am getting a Windows error box that pops up. The top says "R Console: Rgui.exe - Entry Point Not Found" and the text in the box says "The procedure entry point g_intern_static_string could not be located in the dynamic link library libglib-2.0-0.dll." However, when I then click OK on this error box, Rgraphviz appears to finish loading fine: > library(Rgraphviz) Loading required package: graph Loading required package: grid > sessionInfo() R version 2.9.0 (2009-04-17) 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 [8] base other attached packages: [1] Rgraphviz_1.22.1 graph_1.22.2 loaded via a namespace (and not attached): [1] tools_2.9.0 > graphvizVersion() $installed_version [1] '2.20.3' $build_version [1] '2.20.3' I don't really use Rgraphviz, so I don't have any code to see if works completely. I had gotten to this same point a couple of R versions ago, which is where Ernest found my e-mail. I still think I had the Windows error message, which I guess I just ignored as everything I needed to do back then seemed to work. So, should I and others continue to ignore it now if we get to this point? Anything else to try? Writing the "how to install" vignette would really come in handy!!!

1) I agree that the use of the README file is pretty inconvenient. 2) Clearly, the README file is wrong. The way you can always check what you need is the following, read http://bioconductor.org/checkResults/2.4/bioc-LATEST/Rgraphviz /liverpool-checksrc.html (this is the windows build server), where you will see that Rgraphviz (for windows) is build using Graphviz 2.20.3 (But OS X Leopard uses 2.22.2). This is of course really irritating, and I have attempted to remedy this by the install/build message (but see 4) below - it really does not work as well as I thought). 3) The way Graphviz version is set on Windows is pretty unstable... 4) While I have added the build/install check, it currently fails if you are using Graphviz 2.22 because the DLL fails to load. I have some ideas on how to fix this, but I need to brush up on my knowledge on exactly how DLLs are loaded, to see if it is possible to catch this at an earlier stage. Essentially, I need to fix this in the coming days (weeks). There has been (too many) emails on this in the last couple of days, so it has certainly been pushed up my priority schedule. Finally, I have no idea why you get the error when you load Rgraphviz. If you can successfully run R> example(layoutGraph) then everything should be working.

Hi There Many thnx for coming back to me & so quickly! Just to add to the plot: 1. I have R2.8.1 also fully loaded on this laptop, but did not bother to populate packages as R2.9.0 was out so quickly - and once loaded I tried to load Rgraphviz on R2.9.0 ~ to no avail 2. However, I have Rgraphviz running on my home laptop also on Windows XP on R2.8.1, and yesterday boldly copied all library files on Rgraphviz to my work laptop (Windows XP) now under R2.8.1 and voila it's running and also tested the R> example(layoutGraph) > example(layoutGraph) lytGrp> library(graph) lytGrp> set.seed(123) lytGrp> V <- letters[1:10] lytGrp> M <- 1:4 lytGrp> g1 <- randomGraph(V, M, 0.8) lytGrp> x <- layoutGraph(g1) lytGrp> library(graph) 3. No same luck on R2.9.0!

Hi Kasper, I can successfully run example(layoutGraph), so that's good. The Windows error box might be related to Graphviz itself - in the past there was some information on the www.graphviz.org about the error (don't remember if it was the same error as now, although it was the same error as I was having at the time), but it's gone now. Their suggested fix at the time didn't work either, so maybe that's why they removed it! I'm going to be doing some network analysis, so I'll probably be using Rgraphviz to make the network plots. Hopefully there will be no problems except for the irritating error box every time. Thanks for all your work on this!
