Hello there, I am trying to run Rgraphviz on my Linux box with redhat 7.3. I thought I have followed the special instruction for installing Rgraphviz on the BioConductor website: I installed graphviz 1.10 before installing Rgraphviz. The installation of Rgraphviz was sucessful. The problem is that I can not open Rgraphviz library. Below is the error message. Any help will be appreciated. Thanks. Yuzhen >library(Rgraphviz) Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library "/usr/local/lib/R/library/Rgraphviz/libs/Rgraphviz.so": libdotneato.so.0: cannot open shared object file: No such file or directory Error in library(Rgraphviz) : .First.lib failed
