Thanks - you came before me. I get the same error but managed to work around.

This is likely caused by the upgrade of ess, as I realized it after
upgrading to ess 14.09.

You can work around by 
1) evaluating the R code which gives the error message
2) quitting the R session
3) re-starting the R session manually in the same window (where the old
R session was)

I also send this to the ess mailing list.

Cheers,

Rainer
