Hi Eric:

Thanks a lot!   It would be nice if Org-Babel model could automatically add the "#+ATTR_LaTeX" lines (from the hint in the R code header line) during LaTeX export.

Somehow I failed to compile the file on my system.  It seems the line:

#+ATTR_LaTeX: width=5px

has corrupted the PDF file generated in R.   Because after "C-c C-e d",  I get the following error:

!pdfTeX error: pdflatex (file ./a3.pdf): PDF inclusion: required page does not exist <0>
 ==> Fatal error occurred, no output PDF file produced!

and  I could not open the PDF file of the R plot any more (the error message is "Cannot display this page! Maybe because of a conversion failure").  

Attached is the simplified org file that failed on "LaTeX transport" on my computer. 

Thanks! 

Sincerely,
Feiming Chen

Hi Feiming,

The "width" and "height" header arguments are passed to R to affect the
size of the generated file e.g.,

  png(filename="a1.png",width=500,height=500)

however they do not affect the generated latex code.  Luckily Org-mode
does support passing information like image width to latex figures.  See
my attached version of your test file which uses #+ATTR_LaTeX lines to
specify the width during LaTeX export.

Best -- Eric
