excluder (version 0.5.1)

exclude_ip: Exclude IP addresses from outside of a specified country.

Description

The exclude_ip() function removes rows of data that have IP addresses from outside the specified country. The function is written to work with data from Qualtrics surveys.

Usage

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

Value

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

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.

silent

Logical indicating whether to print message to console. Note this argument controls the exclude message not the check message.

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.

  exclude_ip()

# Exclude IP addresses outside of Germany
df <- qualtrics_text %>%
