R devel - Aug 2008 - problems with plotting of graphNEL (PR#11993)

Full_Name: Christian Kuehnert
Version: 2.7.1
OS: Windows XP
Submission from: (NULL) (91.14.237.109)


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

- Ask on the bioconductor list, as this is a problem with a
  bioconductor package

  http://bioconductor.org/docs/mailList.html

- provide the output of sessionInfo() so that the specifics of your
  package version and other aspects of your system are transparent

- provide a short cut-and-paste example of the problem (the vignettes
  of each bioconductor package are built every night on 5 different
  platforms, so if this were a general problem it would have been
  noticed).

- as a shot in the dark, have you tried to update your packages to
  their most recent version, e.g., following the instructions at

  http://bioconductor.org/download

  ?
