Hi Detlef,

It took me a minute or two to spot the problem, but you've got
the :results header args on the wrong line. They go on the #+begin_src
line, not the #+srcname line (the latter is optional). With that change,
things work as expected. I hope you enjoy R with org-babel, and do let
us know if you have suggestions for improving it.

x <- runif(100)
y <- x + rnorm(100)
summary(lm(y ~x))

lm(formula = y ~ x)
