Having the "library" call in its own block, with results silent, also works.

#+NAME: setup
#+BEGIN_SRC R :session :results silent
library(ascii)
#+END_SRC

#+NAME: test01
#+BEGIN_SRC R :session :results output
numstbl <- table(1:4, 1:4)
summary(numstbl)
#+END_SRC

That's how I usually do things, perhaps because I use "ℝ>" as m prompt and I 
ran into the same problem but found this got around it (though it's been a while 
and I can't remember for sure).  It also saves time when rerunning code because 
I don't reload stuff over and over.
