Export a multistar as a flat table

We can obtain a flat table, implemented using a tibble, from a multistar (which can be the result of a query). If it only has one fact table, it is not necessary to provide its name.

Usage

multistar_as_flat_table(ms, fact = NULL)

# S3 method for multistar
multistar_as_flat_table(ms, fact = NULL)

Arguments

ms

A multistar object.

fact

A string, name of the fact.

Value

A tibble.

Examples

ft <- ms_mrs |>
  multistar_as_flat_table(fact = "mrs_age")

                   attributes = c("city", "state")) |>
  select_dimension(name = "when",
                   attributes = c("when_happened_year")) |>
  select_fact(name = "mrs_age",
              measures = c("n_deaths")) |>
