Values a plot feature actually holds

The distinct stored values of one filterable feature, with the number of plots carrying each. Meant for discovering what can be asked for before passing it to `query_plots(feature_filters = ...)`, and for populating a dropdown in the query app.

Lookup features (`table_colnam`) are resolved to readable names, so the values returned are the ones to filter on.

Usage

plot_feature_values(feature, con = NULL)

Arguments

feature

A single feature name, as listed by [plot_feature_filters()].

con

Optional database connection. If `NULL`, [call.mydb()] is called.

Value

A tibble with `value` and `n_plots`, most widespread value first.

  plot_feature_values("principal_investigator", con = mydb)
} # }
