Extract a dplyr tbl column as a vector

Question

Is there a more succinct way to get one column of a dplyr tbl as a vector, from a tbl with database back-end (i.e. the data frame/table can\'t be subset directly)?

Answer 1

I'd probably write:

collect(select(iris2, Species))[[1]]

Since dplyr is designed for working with tbls of data, there's no better way to get a single column of data.
