ECM follows:

Make a string of three characters :'A', '<TAB>', and 'B':

#+BEGIN_SRC R
res <- paste0("A","\t","B")
nchar(res)
#+END_SRC

#+RESULTS:
: 3

Make a src block in which the string appears literally, then execute the 
resulting src block:

#+BEGIN_SRC R  :results raw :wrap "src R"
   res <- paste0("A","\t","B")
   paste0("nchar(\"",res,"\")")
#+END_SRC

#+RESULTS:
#+BEGIN_src R
nchar("A	B")
#+END_src

#+RESULTS:
: 10

Ouch!

I don't have time to dig into this now, but thought I'd get it on the 
record.
