Hi, I was trying to use cytoscapePlot() from the graphite package, but got the error message below:

> library(graphite)
> cytoscapePlot(convertIdentifiers(reactome$`Unwinding of DNA`, "symbol"))
Loading required package: RCytoscape
Loading required package: XMLRPC
Error in function (type, msg, asError = TRUE)  : couldn't connect to host
In addition: Warning messages:
1: package ‘RCytoscape’ was built under R version 2.15.2 
2: package ‘XMLRPC’ was built under R version 2.15.2


What's the problem here?

thanks!

John
