Find which files can be loaded from an IPUMS extract. On Windows, this is generally a zip file (which you can optionally unzip). On macOS, they are generally unzipped for you, so there will be a directory.
ipums_list_files(
file,
types = NULL,
data_layer = NULL,
shape_layer = NULL,
raster_layer = NULL
)
ipums_list_data(file, data_layer = NULL)
ipums_list_shape(file, shape_layer = NULL)
ipums_list_raster(file, raster_layer = NULL)
