​Hello, My name is zahra. I'm MSC student at Tarbiat Modares University. I have followed the instructions for installing Rgraphviz (on a win 7.0 with R2.14.2) at the following link : >>>>>http://www.graphviz.org/pub/graphviz/stable/windows/graphviz-2.28 .0.msi >>>>> But I get the following error message (after apparently successfully installing Rgraphviz) : >>>>> >>>>>> library(Rgraphviz) >>>>>Loading required package: graph >>>>>Loading required package: grid Error : .onLoad failed in loadNamespace() for 'Rgraphviz', details: call: value[[3L]](cond) error: unable to load shared object 'C:/Users/parisa/Documents/R /win-library/2.14/Rgraphviz/libs/x64/Rgraphviz.dll': LoadLibrary failure: The specified module could not be found. Check that (1) graphviz is installed on your system; (2) the installed version of graphviz matches '2.20.3'; this is the version used to build this Rgraphviz package; (3) graphviz is accessible to R, e.g., the path to the graphviz 'bin' directory is in the system 'PATH' variable. See additional instructions in the 'README' file of the Rgraphviz 'source' distribution, available at http://bioconductor.org/packages/release/bioc/html/Rgraphviz.html Ask further questions on the Bioconductor mailing list http://bioconductor.org/docs/mailList.html Error: package/namespace load failed for ‘Rgraphviz’ what's the libcdt-4.dll ? how can i download and install it on my windows? Thanks a lot [[alternative HTML version deleted]]

It is part of graphviz. As recommended in the Rgraphviz documentation, you may want to install an older version of graphviz, ideally the same version that was used to build Rgraphviz. You can get it here: http://www.graphviz.org/pub/graphviz/stable/windows/graphviz-2.20.3a.m si Then make sure that the graphviz BIN directory is in your system PATH, as suggested by this error message.
