![[Deprecated]](figures/lifecycle-deprecated.svg?package=dplyr&version=1.0.10)
combine() is deprecated in favour of vctrs::vec_c(). combine()
attempted to automatically guess whether you wanted c() or unlist(),
but could fail in surprising ways. We now believe it's better to be explicit.
combine(...)Vectors to combine.
f1 <- factor("a")
f2 <- factor("b")
combine(f1, f2)
# ->
vctrs::vec_c(f1, f1)
combine(list(f1, f2))
# ->
vctrs::vec_c(!!!list(f1, f2))
