I frequently run R code using source() or just paste large chunks of

remainder of the code continues to execute.
Questions:
1) Is there a way to change the color of the error messages from blue
to another color? There are other messages (not error messages) that
are also blue and to have another color would make it easier to spot
errors as the screen scrolls through the code.
No, there isn't.
2) Is there a way to make execution of the sourced or pasted code to
stop immediatelyt if there is an error? I did some research and found
a way to make the whole session end, but that is too radical. I also
tried to change the option error from NULL to stop and that also does
not do the trick: the remaining pasted or sourced code is still
executed.
source() should stop when you get an error. Rather than pasting a lot
of text into the clipboard, if you want it to stop, you could use
source('clipboard')
or
source('clipboard', echo=T)
Any help will be appreciated. I am running R version 2.3.0 on Windows
XP Pro.
My advice would be to upgrade to 2.4.0 (or at least 2.3.1).
