Match Scaling Parameters for Fixation Data

Description

This function matches the scaling parameters of fixation data between a reference table and a source table based on a common matching variable.

Usage

match_scale(
  ref_tab,
  source_tab,
  match_on,
  refvar = "fixgroup",
  sourcevar = "fixgroup",
  window,
  ...
)

Arguments

ref_tab	A data frame containing the reference fixation data.
source_tab	A data frame containing the source fixation data.
match_on	A string specifying the variable name in both 'ref_tab' and 'source_tab' to match on.
refvar	A string specifying the variable name in 'ref_tab' containing the reference fixations (default is "fixgroup").
sourcevar	A string specifying the variable name in 'source_tab' containing the source fixations (default is "fixgroup").
window	A numeric vector of length 2 specifying the time window to restrict the fixations in the source fixation data (default is NULL, which considers all fixations).
...	Additional arguments passed to the 'estimate_scale' function.

Value

A data frame containing the original source fixation data with additional columns for the matched scaling parameters.

Examples

# Example usage of the match_scale function
ref_tab <- # reference fixation data
source_tab <- # source fixation data
matched_data <- match_scale(ref_tab, source_tab, match_on = "subject_id")
