* [BUG] [babel] R graphics header arg :units

Hi all,

I am having troubles in using the header argument :units which is
implemented for R source blocks.  Example:

#+begin_src R :results graphics :file wideplot.png :width 14 :height 7 :units "cm"
  plot(1:10, 1:10)
#+end_src


This expands to

: png(filename="wideplot.png",height=7,units=cm,width=14)
: plot(1:10, 1:10)
: dev.off()

and leads -- when evaluated -- to the error

: Fehler in match.arg(units, c("in", "px", "cm", "mm")) : 
:   'arg' must be NULL or a character vector

I guess this is a bug, correct?  Otherwise, how do I correctly use
this header argument?

Regards,
Andreas

Hi Andreas,

I believe the author of ob-R.el no longer reads the list.  Perhaps you could
propose a patch?

All the best,
Tom

It seems to work if you do this :units "'cm'" :res 100, i.e.:

#+begin_src R :results graphics :file wideplot.png :width 14 :height 7 :units "'cm'" :res 100
  plot(1:10, 1:10)
#+end_src

I can't comment on whether it is a bug or not.

Thanks for this!  I had only tried :units '"cm"'...  Your example works
fine here.

Best,
Andreas

Aloha all,

The attached patch handles quoted string values for R device header
arguments.  With the patch the following works as expected:

#+header: :width 100 :height 100 :units "mm" :res 120
#+BEGIN_SRC R :results graphics :file "test.png"
x <- c(1,2,3,4,5)
y <- x
plot(x,y)
#+END_SRC

All the best,
Tom

Hi Tom,

very nice.  With your patch I can confirm the :units argument accepts
quoted strings!

Thanks a lot,
Andreas
