Hello, 

I've installed the package RBGL (and XML and Rgraphviz) and tried to follow the
examples in the RBGL-manual 

http://bioconductor.org/packages/2.2/bioc/vignettes/RBGL/inst/doc/RBGL.pdf

But when I try to plot the graph using e.g. 

plot(dijk)

an error message occurs: 

"Error in as.double(y): cannot coerce type 'S4' to vector of type 'double'.

Can anyone tell me what I can do to solve this problem? 
Thanks very much!
Christian
