mark_ip: Mark IP addresses from outside of a specified country.

In excluder: Checks for Exclusion Criteria in Online Data

Mark IP addresses from outside of a specified country.

Description

The mark_ip() function creates a column labeling rows of data that have IP addresses from outside the specified country. The function is written to work with data from Qualtrics surveys.

Usage

mark_ip(
  x,
  id_col = "ResponseId",
  ip_col = "IPAddress",
  rename = TRUE,
  country = "US",
  include_na = FALSE,
  quiet = FALSE,
  print = TRUE
)

Arguments

x	Data frame or tibble (preferably imported from Qualtrics using {qualtRics}).
id_col	Column name for unique row ID (e.g., participant).
ip_col	Column name for IP addresses.
rename	Logical indicating whether to rename columns (using rename_columns())
country	Two-letter abbreviation of country to check (default is "US").
include_na	Logical indicating whether to include rows with NA in IP address column in the output list of potentially excluded data.
quiet	Logical indicating whether to print message to console.
print	Logical indicating whether to print returned tibble to console.

Details

To record this information in your Qualtrics survey, you must ensure that Anonymize responses is disabled.

Default column names are set based on output from the qualtRics::fetch_survey(). The function uses ipaddress::country_networks() to assign IP addresses to specific countries using ISO 3166-1 alpha-2 country codes.

The function outputs to console a message about the number of rows with IP addresses outside of the specified country. If there are NAs for IP addresses (likely due to including preview data—see check_preview()), it will print a message alerting to the number of rows with NAs.

Value

An object of the same type as x that includes a column marking rows with IP addresses outside of the specified country. For a function that checks these rows, use check_ip(). For a function that excludes these rows, use exclude_ip().

Note

This function requires internet connectivity as it uses the ipaddress::country_networks() function, which pulls daily updated data from https://www.iwik.org/ipcountry/. It only updates the data once per session, as it caches the results for future work during the session.

Examples

# Mark IP addresses outside of the US
data(qualtrics_text)
df <- mark_ip(qualtrics_text)

# Remove preview data first
df <- qualtrics_text %>%
  exclude_preview() %>%
  mark_ip()

# Mark IP addresses outside of Germany
df <- qualtrics_text %>%
  exclude_preview() %>%
  mark_ip(country = "DE")
