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,
