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?
Well, it is nonsense to use it, but works since TRUE is coerced to 1 as in:
list(list(11, 12), 13)[[c(TRUE, TRUE)]]
In your example will also fail with integers without a chance to do the
recursion.
