[igraph] igraph with rscript.exe

[Renger van Nieuwkoop]

Hi

I am running R2.10 and the latest version of igrahp on a Windows 7 64-machine.

I have a R-Script that runs fine in the GUI of R, but if I run it with rscript.exe in a dos-window I get an error:

Error in graph.adjacencyy(djm, weighted = TRUE, mode=”directed”):

Could not find function “is”

(original in German  konnte Funktion “is” nicht finden)

Any idea what could cause this problem?

Thanks

Renger
