Hi, I am installing Bioconductor 1.4. I am having some problems with Rgraphviz. I installed the graphviz software and set the LIB_PATH_DIR to include the dir with the graphviz libraries. I then run "R INSTALL Rgraphviz". Everything looked pretty. But when I go to R: > 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": /usr/local/lib/R/library/Rgraphviz/libs/Rgraphviz.so: undefined symbol: gvNEWcontext Error in library(Rgraphviz) : .First.lib failed Any help would be greatly appreciated, Rodrigo
