[tech-spec] R Gedankenexperiment

Something that comes up often in my R fiddling, and that I haven't
settled on a 'best practice' for, is 'get the next X [from vector A]
after Y [from vector B]'
Idea is to mesh trade 'entries' from A and 'exits' from B
A reworked tidbit from one of Tom's programs, with apologies to him:
exit <- unlist( sapply( entry, function(x) min( which( event> x))))
And I've independently found myself writing very similar lines
[although 'anonymous functions' are against my religion, but that's a
matter of style]
But is there a better way? Anyone up for a Gedankenexperiment?
Thanks, SW
