Import a folder of Gazepoint Biometrics exports — import_gazepoint_biometric

Reads rectangular Gazepoint CSV exports from a folder and combines files that contain at least one known Gazepoint Biometrics column. This function is designed for all-gaze and fixation-style exports. Multi-section Gazepoint Data Summary files should be parsed separately.

Usage

import_gazepoint_biometric_folder(
  path,
  pattern = "\\.csv$",
  recursive = FALSE,
  include_fixations = TRUE,
  include_all_gaze = TRUE,
  include_other_csv = FALSE,
  na = c("", "NA", "NaN")
)

Arguments

path: Folder containing Gazepoint CSV exports.
pattern: Regular expression used to identify candidate CSV files.
recursive: Should subfolders be searched?
include_fixations: Should files with "fixation" in the file name be included?
include_all_gaze: Should files with "all_gaze" in the file name be included?
include_other_csv: Should other CSV files be attempted? The default is FALSE to avoid accidentally trying to parse multi-section Data_Summary_export files as rectangular data.
na: Values that should be treated as missing.

Value

A data frame with all imported rows combined. The output includes a source_file column and has class "gazepoint_biometrics_folder".
