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

[Giuseppe Pagnoni]

Sorry, I just sent you the reply that was meant for Berry's advice :-).  Your suggestion also looks very useful, but somehow the png files do not get saved (in the current directory or elsewhere), and I actually do not get any error messages in the R buffer (I also tried to change the file type to jpeg).  Any idea why?

thanks again

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
