ess-remote

[Bud Gibson]

I am using the ess package downloaded as a package from xemacs.org.  I 
am on xemacs 21.4 from April 2001.  It came with Redhat 7.3.  When I run 
ess-remote, things seem to start up ok.  However, I cannot send buffers 
to be evaluate in the ess process (I am running R1.6.1 remotely on a 
linux box).  I get this error

Wrong type argument: stringp, nil

About one line of the file appears to be evaluated.  Here is the 
transcript of my ess-remote session if that helps.  Thanks in advance, Bud
