I wanted to use it for lectures, where it would be very nice to have
the code and the result.

Right - so I decided to use a different approach (see attached file
BeamerSweaveExample3.lyx) which is working.

My question is just: why is "Slide 2" working, but "Slide 1" or "Slide
3" not, when I say "echo=TRUE"?

I don't have a problem usoing ERT boxes, but I know others, who would
prefer the approch used for "Slide 1" or "Slide 3" using the Frame
environment.

As I said, I am not using it any more.

No - I took the plain frame \lyxframeplain, and changed "plain" to "fragile".

I got it working, but am not entirely happy.
