enrich_dimension_import_test: Import 'tibble' to test to enrich a dimension

In starschemar: Obtaining Stars from Flat Tables

Import tibble to test to enrich a dimension

Description

For a dimension of a star schema a tibble is attached. This contains dimension attributes and new attributes. If values associated with all rows in the dimension are included in the tibble, the dimension is enriched with the new attributes. This function checks that there are values for all instances. Returns the dimension instances that do not match the imported data.

Usage

enrich_dimension_import_test(st, name = NULL, tb)

## S3 method for class 'star_schema'
enrich_dimension_import_test(st, name = NULL, tb)

Arguments

st	A star_schema object.
name	A string, name of the dimension.
tb	A tibble object.

Value

A dimension object.

Examples

tb <-
  enrich_dimension_export(st_mrs_age,
                          name = "when_common",
                          attributes = c("week", "year"))

# Add new columns with meaningful data (these are not), possibly exporting
# data to a file, populating it and importing it.
tb <- tibble::add_column(tb, x = "x", y = "y", z = "z")[-1, ]

tb2 <- enrich_dimension_import_test(st_mrs_age, name = "when_common", tb)
