âHello,
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
