query re ">" in Sweave output for Mac input

Dear R Mac users, When writing examples for students, I typically use Sweave to integrate the R code with the output. R code from Sweave conventionally is preceded by the prompt character (typically ">"). Although this can be suppressed in Sweave, it seems as if the conventional style is to include the prompt on every example line. This leads to a syntax error on every line copied from a Sweave example directly into R. Now my question: Is there some option in the Mac R-Gui that I have missed that allows me to directly paste Sweave output of commands (i.e., including the prompt) into R without first editing them out in the editor? I think that this is possible in Windows (but have only been told that by my students). If it is not possible, then what do people think about example code not including the prompt? It makes it easier to cut and paste from sample text, but makes it harder to spot the code in the sample text. (For my web based examples I get around this by color coding the R commands , but I am worrying about pdf examples).
Do you know of R CMD Stangle <filename>.Rnw which extracts the R code into a file <filename>.R?
