Thanks, that is in fact exactly what I need.  Looking at the
documentation again, I see that it says:

"Some languages including R, gnuplot, dot, and ditaa provide special
handling of the :file header argument automatically wrapping the code
block body in the boilerplate code required to save output to the
specified file. This is often useful for saving graphical output of a
code block to the specified file."

I just didn't understand this at first.  Maybe the following sentence
should/could be added:

"... the specified file.  This means that the argument of the :file
header can be omitted and the file name can be generated within the
source block."

Cheers,

Loris
