[R-SIG-Mac] help on loading RGraphviz

[William Revelle]

Dear Mac R list,

I am trying to load RGraphviz so that I can use Graphviz directly 
from R rather than as a stand alone program.

Following (I think) the advice given to the list in August, I have 
installed Graphviz-2.8 from the att site and the bioconductor 
packages from Bioconductor lite.

(from http://www.arcknowledge.com/gmane.comp.lang.r.mac/2006-08/msg00044.html)

>  To install Rgraphviz on OSX when using the binary installation of R
>  downloaded from CRAN (that is, the R app), do the following:
>
>  1. Install the _graphviz_ binary from http://r.research.att.com/.
>
>  2. Install the _binary_ version of the BioC Rgraphviz package:
>
>       source("http://bioconductor.org/biocLite.R";)
>       biocLite("Rgraphviz")

Did that.


However, when I try to load Rgraphviz I get the following error message:

Loading required package: graph
Loading required package: geneplotter
Loading required package: annotate
Loading required package: Biobase
Loading required package: tools

There are a variety of followups to the August set of posts, but 
nothing that seems to directly help.

Any help would be appreciated.

Thanks.

Bill
