Import tibble
to test to enrich a dimension
Source: R/star_schema_enrich_dimension.R
enrich_dimension_import_test.Rd
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 star_schema
enrich_dimension_import_test(st, name = NULL, tb)

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)
