Compare collections (per-collection summary)

Usage

entropia_compare_collections(x, by = "collection_name")

Arguments

x

A data frame or tibble with a collection column.

by

The collection column, selected by name or bare (tidyselect). Default "collection_name".

Value

A tibble with the by column, n_items/n_assets (when x carries those id columns) and n, ordered by the collection column.

Details

Summarises a collected tibble one row per collection. The natural input is the collected corpus (dplyr::collect(entropia_corpus(con))), which carries collection_name, item_id and asset_id; pass by to group by a different collection column (e.g. collection_id).

Each row reports n (rows of x in that collection) plus n_items and n_assets (distinct item_id / asset_id values, NA excluded) when the input carries those columns. On the collected corpus n equals the number of assets in the collection. Rows are ordered by the collection column (deterministic).

Examples

con <- entropia_connect(system.file("extdata", "entropia-example.sqlite",
  package = "entropiaR"
))
corpus <- entropia_collect(entropia_corpus(con))
entropia_compare_collections(corpus)
