You are not expected to. I usually copy and paste from an external editor, and rarely use source. Both S(-PLUS) and R have long had modes for editors allowing much more than the S-PLUS script windows: indeed they were copied from such modes. Take a look at

http://cran.r-project.org/other-software.html

In ESS (and I believe R-WinEdt) you can submit code by highlighting and using an editor command.

You can already display a file in RGui using the File menu, and highlight lines there and submit them. If you want to change them, use up-arrow and edit them in the commands buffer.

You could also try the R-devel prerelease (on CRAN), as it can edit such a displayed file.
