ipumsr now supports IHGIS!
IPUMS spatial data users now have programmatic access to international census data tables in IHGIS. The recent release of ipumsr 0.9.0 enables users to explore metadata; build, submit, and download extracts; and read IHGIS tables directly in R. Many of the ipumsr functions that had been NHGIS-specific have now been generalized to accommodate both IHGIS and NHGIS. More information on the new functions can be found in the ipumsr changelong.
