Several graphs in R

Several graphs in R

Hi

I just solved a problem of mine, i.e. how to deal with multiple graphs
generated in an R script.

OK - all are saved into separate pdfs in separate paths. But I would
like to see them after they are generated - and this is my solution:

#+begin_src R :results output
  path <- "./"
  for (i in 1:10) {
    fn <- paste(path, "/", "graph-", i, ".pdf", sep="")
    pdf(fn)
    try(
         plot(runif(100))
       )
    dev.off()
    cat("[[", fn, "]]\n", sep="")   #<======= here it is!
  }
#+end_src

Then in the results bluck, there will be links to all pdfs.

Thought this might help somebody.

Cheers,

Rainer

Hi Rainer,

Cool. You might want to experiment with 

 :results output raw
 :results output org

also (I suspect that strictly speaking those links should not be
functioning as links inside an example block).

Feel free to add useful tricks like this to the babel R page:

Good idea - I'll try it out - although I quite like it to be in a
results block - so it is a clear that it results from the code above.

If you tell me how, I could do it.
