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 |
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()
.
