Hello Bioconductor! 

I wanted to use the Rgraphviz package, as it would be very useful for me to
visualize graphs and networks. However, I always get an Error message when I
type in 

>library(Rgraphviz)

 

>Error in inDL(x, as.logical(local), as.logical(now), ...) : 

>kann shared library
'C:/PROGRA~2/R/R-27~1.2/library/Rgraphviz/libs/Rgraphviz.dll' nicht laden:

> LoadLibrary failure:  Das angegebene Modul wurde nicht gefunden.

 

>Error : .onLoad in 'loadNamespace' für 'Rgraphviz' fehlgeschlagen

>Fehler: Laden von Paket/Namensraum für 'Rgraphviz' fehlgeschlagen

 

Which basically means that the package cannot be loaded and the modul was
not found. Additionally, an error window pops up, saying that there the file
“cdt.dll” was not found and the package shall be re-installed. 

I tried to install the package several times in different versions of R, and
during the installation there are no problems. What is the cause for the
problem I have? As many other package also use Rgraphviz, there seems to be
no alternative, is there?

 

Thank you for your help!

 

Best wishes

Fatima
