Dear all,

I need help on the install of Rgraphviz after install my new version of R.
R2.12.0 crashed after I trying to plot using Rgraphviz package.
Details are:


 >library("Rgraphviz")
Loading required package: graph
Loading required package: grid

/> set.seed(123) /
/> V <- letters[1:10] /
/> M <- 1:4 /
/> g1 <- randomGraph(V, M, 0.2) /
//

but when I tried to plot it R crashed.

/> plot(g1) /

My working environments are:


 > R.version.string
[1] "R version 2.12.0 (2010-10-15)"
 > win.version()
[1] "Windows Vista (build 6001) Service Pack 1"
 >
 >  packageDescription("Rgraphviz")$Version
[1] "1.28.0"
 > graphvizVersion()
$installed_version
[1] '2.20.3'

$build_version
[1] '2.20.3'

and I do add the "C:\\Program Files\\Graphviz2.20\\Bin" into PATH of 
environment


 > strsplit(Sys.getenv("PATH"), ";")
