dplyr: A Grammar of Data Manipulation

#' Band membership
#'
#' These data sets describe band members of the Beatles and Rolling Stones. They
#' are toy data sets that can be displayed in their entirety on a slide (e.g. to
#' demonstrate a join).
#'
#' `band_instruments` and `band_instruments2` contain the same data but use
#' different column names for the first column of the data set.
#' `band_instruments` uses `name`, which matches the name of the key column of
#' `band_members`; `band_instruments2` uses `artist`, which does not.

#' @format Each is a tibble with two variables and three observations
