> c("a","b")[[c(TRUE,FALSE)]]
Error in `[[.default`(factor(c("a", "b")), c(TRUE, FALSE)) : 
  recursive indexing failed at level 1

I find this error message confusing, though after reading the HELP carefully I
think I know what is going on. Would not something like "[[ does not work with
logical index vectors" be more appropriate?
