mark_location: Mark locations outside of US

In excluder: Checks for Exclusion Criteria in Online Data

Mark locations outside of US

Description

The mark_location() function creates a column labeling rows that have locations outside of the US. The function is written to work with data from Qualtrics surveys.

Usage

mark_location(
  x,
  id_col = "ResponseId",
  location_col = c("LocationLatitude", "LocationLongitude"),
  rename = TRUE,
  include_na = FALSE,
  quiet = FALSE,
  print = TRUE
)

Arguments

x	Data frame (preferably imported from Qualtrics using {qualtRics}).
id_col	Column name for unique row ID (e.g., participant).
location_col	Two element vector specifying columns for latitude and longitude (in that order).
rename	Logical indicating whether to rename columns (using rename_columns())
include_na	Logical indicating whether to include rows with NA in latitude and longitude columns 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 only works for the United States. It uses the #' maps::map.where() to determine if latitude and longitude are inside the US.

The function outputs to console a message about the number of rows with locations outside of the US.

Value

An object of the same type as x that includes a column marking rows that are located outside of the US and (if include_na == FALSE) rows with no location information. For a function that checks for these rows, use check_location(). For a function that excludes these rows, use exclude_location().
