[Rd] bug or feature? (PR#4150)

[w.huber at dkfz-heidelberg.de]

Hi Axel,

You may wish to consult the man page for the '==' operator and the
'identical' function.

[1] FALSE

And probably your notion of a "bug" is too wide: please have a look at the
section "R Bugs", 9.1 in the R FAQ.

Best regards
   Wolfgang
