ipumsr (version 0.4.5)

ipums_list_files: List files available for analysis in an IPUMS extract

Description

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.

Usage

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)

Arguments

types

One or more of "data", "shape", or "raster" indicating what type of files to look for.

data_layer

dplyr select-style notation for the data files to look for

shape_layer

dplyr select-style notation for the shape files to look for

raster_layer

Value
