hipread

hipread (hierarchical IPUMS reader) is a fork from tidyverse readr that allows for reading hierarchical fixed width text files, like those created by the CSPro software and commonly used by census data providers.

Compared to readr it is:

• Able to natively read the "hierarchical" fixed width file format that IPUMS and some other census data providers use. These files can have multiple types of observations in them, each with their own specification of variables.

• Better at reading gzipped data. It does not require loading the full file into a raw vector, which takes a large amount of memory, and prevents reading gigantic files altogether (because R can only store raw vectors of a certain size).

• Less flexible. It only works on fixed width files, only accepts data of types character, double and integer, and is less detailed about the information it gives about parsing failures. This makes it easier for me to maintain.

I do not expect that this will be directly useful for too many people, so the documentation is a little bit light. Instead I expect most users will use this package through the ipumsr package. But, if you are interested and find something confusing, please let me know!
