This is usually a symptom of a version mismatch between the version of
graphviz used to build Rgraphviz, and the version of graphviz found when
Rgraphviz is loaded.
My guess is that you have graphviz 2.18 installed, but need 2.16.1 to
match the version used to build windows Rgraphviz available through
biocLite.
Here's the link to the correct graphviz

Hi,
since my package oneChannelGUI suggests Rgraphviz I realized that, in
Bioconductor 2.2 release, the windows version for Rgraphviz
is not available due to an error in compilation example compilation.
checking examples ... ERROR
Running examples in 'Rgraphviz-Ex.R' failed.
The error most likely occurred in:
### * agwrite
flush(stderr()); flush(stdout())
### Name: agwrite
### Title: A function to write a Ragraph object to a file
### Aliases: agwrite agread
### Keywords: graphs
### ** Examples
V <- letters[1:10]
M <- 1:4
g1 <- randomGraph(V, M, .2)
z <- agopen(g1,"foo",layout=FALSE)
Actually I got around using the Rgraphviz from bioconductor 2.1, but I
would like to know if it will be possible to fix the error.
Cheers
