[R] a fix for rotated PDF graphs

[Prof Brian Ripley]

The problem is simply that you are using epstopdf incorrectly.  This is 
not an R issue but the correct solution has been discussed here before
(although my quick searches failed to locate it in the archives).

First, if you want `PDF graphs' you can make them in R with the pdf() 
device.  I am very surprised you did not mention that.

Second, if you insist on using distiller or gs (via epstopdf) you need to
unset the option that rotates plots automatically.  It's documented in 
ps2pdf.htm:

  By default Ghostscript determines viewing page orientation based on the 
  dominant text orientation on the page. Sometimes, when the page has text 
  in several orientations or has no text at all, wrong orientation can be 
  selected.

  Acrobat Distiller parameter AutoRotatePages controls the automatic 
  orientation selection algorithm. On Ghostscript, besides input stream, 
  Distiller parameters can be given as command line arguments. For 
  instance: -dAutoRotatePages=/None or /All or /PageByPage.

You want /None.

No, it's user error.  You asked gs to rotate them.
