ipumsr 0.8.0

Breaking changes + deprecations

• Collection-specific definition functions for IPUMS microdata projects
  have been deprecated in favor of define_extract_micro(). This
  streamlines syntax across all supported microdata collections. Use the
  collection argument to specify the collection for your
  microdata extract.

  IPUMS NHGIS extracts are still created with
  define_extract_nhgis().

• Previously deprecated methods for retrieving extract history are now
  defunct. Use get_extract_history() instead.

New features

• Adds support for IPUMS API extract endpoints for IPUMS Time Use and
  IPUMS Health Surveys projects! This includes:

  • IPUMS Time Use

    • IPUMS ATUS ("atus")

    • IPUMS AHTUS ("ahtus")

    • IPUMS MTUS ("mtus")

  • IPUMS Health Surveys

    • IPUMS NHIS ("nhis")

    • IPUMS MEPS ("meps")

• Adds support for new rectangularization options for certain
  microdata collections. Use the rectagular_on argument in your
  extract definition to rectangularize on records other than person
  ("P") records.

• Time use variables can be included in IPUMS Time Use extracts. Use
  the tu_var_spec() helper with the time_use_variables argument of
  define_extract_micro() to create a time use variable
  specification.

  This includes both IPUMS-defined and user-defined time use variables. Note
  that user-defined time use variables cannot currently be created via API.
  However, if you have defined a time use variable through the IPUMS web
  interface, you can request it in an extract via API.

• Sample members can be specified in IPUMS ATUS extracts. Use the
  sample_members argument of define_extract_micro() to do so.

• "household_only" is now a supported value for data_structure in
  IPUMS USA extracts.

Minor improvements and fixes

• Fixes bug in add_to_extract.micro_extract() that caused an error if a user
  attempted to update the value of data_quality_flags in a detailed variable
  specification.
