[R-SIG-Mac] query re ">" in Sweave output for Mac input

[William Revelle]

Doug,

I don't think Stangle is what I am looking for, for I want my 
students to read (e.g.) a chapter I am writing (set in pdf after 
Sweave and LateX), copy the R code from the chapter and then run it.

I can just  have the Sweave not issue the prompt for every line, but 
that seems to violate the conventional style of writing examples.

Thanks

Bill
