The interactive() predicate is helpful in scripted environments. I sometimes also invoke R with '--quiet' and am unable to suppress messages from my own startup code as I cannot test if this flag was set or not. (I can work around it by setting an additional environment variable, but that is clunky.) For me '--quiet' is independent to 'interactive'.
R carries the state internally in the integer variable R_Quiet, so a minimal patch only needs to expose an accessor 'quiet()' model after 'interactive()'. Then we get the desired behaviour: ~/svn/r-devel$ RD -q > quiet() [1] TRUE > and this is similarly FALSE in a normal startup without '-q'. Would this change be of interest? The patch is just a few lines (but does not yet contain Rd file changes).
