ipums_website: Launch a browser window to an IPUMS metadata page

In ipumsr: An R Interface for Downloading, Reading, and Handling IPUMS Data

Launch a browser window to an IPUMS metadata page

Description

Launch the documentation webpage for a given IPUMS project and variable. The project can be provided in the form of an ipums_ddi object or can be manually specified.

This provides access to more extensive variable metadata than may be contained within an ipums_ddi object itself.

Note that some IPUMS projects (e.g. IPUMS NHGIS) do not have variable-specific pages. In these cases, ipums_website() will launch the project's main data selection page.

Usage

ipums_website(
  x,
  var = NULL,
  launch = TRUE,
  verbose = TRUE,
  homepage_if_missing = FALSE,
  project = deprecated(),
  var_label = deprecated()
)

Arguments

x	An ipums_ddi object or the name of an IPUMS project. See ipums_data_collections() for supported projects.
var	Name of the variable to load. If NULL, provides the URL to the project's main data selection site.
launch	If TRUE, launch a browser window to the metadata webpage. Otherwise, return the URL for the webpage.
verbose	If TRUE, produce warnings when invalid URL specifications are detected.
homepage_if_missing	If TRUE, return the IPUMS homepage if the IPUMS project in x is not recognized.
project	Please use x instead.
var_label	Variable label for the provided var. This is typically obtained from the input ipums_ddi object and is unlikely to be needed.

Details

If launch = TRUE, you will need a valid registration for the specified project to successfully launch the webpage.

Not all IPUMS variables are found at webpages that exactly match the variable names that are included in completed extract files (and ipums_ddi objects). Therefore, there may be some projects and variables for which ipums_website() will launch the page for a different variable or an invalid page.

Value

The URL to the IPUMS webpage for the indicated project and variable (invisibly if launch = TRUE)

Examples

ddi <- read_ipums_ddi(ipums_example("cps_00157.xml"))

## Not run: 
# Launch webpage for particular variable
ipums_website(ddi, "MONTH")

## End(Not run)

# Can also specify an IPUMS project instead of an `ipums_ddi` object
ipums_website("IPUMS CPS", var = "RECTYPE", launch = FALSE)

# Shorthand project names from `ipums_data_collections()` are also accepted:
ipums_website("ipumsi", var = "YEAR", launch = FALSE)
