Description

Define an IPUMS USA extract request to be submitted via the IPUMS microdata extract API. For an overview of ipumsr microdata API functionality, see vignette("ipums-api", package = "ipumsr").

Usage

define_extract_usa(
  description,
  samples,
  variables,
  data_format = c("fixed_width", "csv", "stata", "spss", "sas9"),
  data_structure = "rectangular",
  rectangular_on = "P"
)

Value

An object of class c("usa_extract", "ipums_extract")

containing the extract definition.

Arguments

description

Description of the extract.

samples

Character vector of samples to include in the extract. Samples should be specified using the sample ID values.

variables

Character vector of variables to include in the extract.

data_format

The desired format of the extract data file (one of "fixed_width", "csv", "stata", "spss", or "sas9").

data_structure

Currently, this must be "rectangular", which is also the default. In the future, the API will also support "hierarchical" extracts.

rectangular_on

Currently, this must be "P", indicating that the extract will be rectangularized on person records. In the future, the API will also support household-only extracts (rectangular_on = "H").
