mark_resolution {excluder}

Mark unacceptable screen resolution

Description

The mark_resolution() function creates a column labeling rows that have unacceptable screen resolution. The function is written to work with data from Qualtrics surveys.

Usage

mark_resolution(
  x,
  res_min = 1000,
  width_min = 0,
  height_min = 0,
  id_col = "ResponseId",
  res_col = "Resolution",
  rename = TRUE,
  quiet = FALSE,
  print = TRUE
)

Arguments

x

Data frame (preferably imported from Qualtrics using {qualtRics}).

res_min

Minimum acceptable screen resolution (width and height).

width_min

Minimum acceptable screen width.

height_min

Minimum acceptable screen height.

id_col

Column name for unique row ID (e.g., participant).

res_col

Column name for screen resolution (in format widthxheight).

rename

Logical indicating whether to rename columns (using rename_columns())

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 insert a meta info question.

Default column names are set based on output from the qualtRics::fetch_survey().

The function outputs to console a message about the number of rows with unacceptable screen resolution.

Value

An object of the same type as x that includes a column marking rows that have unacceptable screen resolutions. For a function that checks for these rows, use check_resolution(). For a function that excludes these rows, use exclude_resolution().
