Hello list,

Using ubuntu 7.04, R 2.6.1 I was unable to load Rgraphviz (despite error free installation / compilation using biocLite). Trying to do so resulted in:

> library(Rgraphviz)
Loading required package: graph
Error in dyn.load(file, ...) : 
  unable to load shared library '/usr/local/lib/R/site-library/Rgraphviz/libs/Rgraphviz.so':
  libgvc.so.2: cannot open shared object file: No such file or directory
Error : .onLoad failed in 'loadNamespace' for 'Rgraphviz'
Error: package/namespace load failed for 'Rgraphviz'

graphviz is installed. In /usr/lib/graphviz there is a link called libgvc.so.2 to libgvc.so.2.0.0

Copying libgvc.so.2.0.0 from /usr/lib/graphviz to /usr/local/libs/R/site-library/Rgraphviz/libs seemed to solve the problem. I can now plot goGraphs!

Hope this helps anyone else with a similar problem.

cheers

iain
