Maybe not what you are looking for, but you could handle the assembly of
the filename within your code block.

Something like:

#+HEADER: :var year=2011 :session *r* :results file
#+begin_src R
  filename <- paste0("time-elapsed-", year, ".pdf")
  
  pdf(filename)
    ## your code
  dev.off()
  
  filename
#+end_src

Andreas
