Re: Output of R code block: only text or plot but not both? And only one "result" can be output?

Many thanks.  Since I am using this within an org-mode notebook, I think the :session trick works well enough for me.

We currently do not have automatic way to do it, so that the resulting
plots are inserted as previewable file links.  However, in addition to
the approach with several :session source blocks proposed by Berry, you
can do it by hand in R:

#+begin_src R :results output raw drawer :dir ./
  x <- rnorm(100)
  print(mean(x))
  png(file="hist1.png")
  hist(x)
  png(file="hist2.png")
  hist(x^2)
  print("[[./hist1.png]]")
  print("[[./hist2.png]]")
#+end_src
