The Posting Guide suggests you include dump("x", file=stdout())

I have a simple x object in my workspace:

 > dump("x", file=stdout())
x <-
c(0, 0, 1, 1, 1, 1)

After reading again the Posting Guide, I am not sure about csv  
attachments, but I can try a simple test. I am removing your address  
(which probably would have accepted the attachment) and leaving only  
the r-help address. If you see an attachment then csv's are accepted.
