* Evaluation of R code block depends on case of keywords???

Greetings.  I happened to notice that in evaluating R source-code blocks in an
Org-Mode file I got some cruft from my .Rprofile in the output on some
occasions but not on others.

To my surprise, it appears that the CASE of the keywords on the BEGIN_SRC line
affects the output.  Please see the appended for a simple example.

I haven't been able to find this behavior documented any place, but of course
it's possible I just missed it.

Can somebody confirm/deny that Org-Mode is SUPPOSED to behave this way?

Thanks,

-- Mike

Hi Mike,

I believe what is happening is that :RESULTS and :EXPORTS are not
recognized, so :results (the correct header argument) defaults to value.

hth,
Tom

Thanks, Tom.  I think your explanation is correct.  The manual page:

    http://orgmode.org/manual/Specific-header-arguments.html#Specific-header-arguments

does indeed show all of the arguments in lower case.  I had seen BEGIN_SRC and
begin_src used interchangeably and so assumed that same latitude applied to
the keywords.  And I have a slight preference for putting keywords in upper
case and values in lower case, just to distinguish one class of things from
the other.  My bad.
