Compute Similarity Between Scanpaths

Description

This function computes the similarity between two scanpaths using a specified method.

Usage

## S3 method for class 'scanpath'
similarity(
  x,
  y,
  method = c("multimatch"),
  window = NULL,
  screensize = NULL,
  ...
)

Arguments

x	A data frame containing the first scanpath.
y	A data frame containing the second scanpath.
method	A character string specifying the method to compute the similarity (default is "multimatch").
window	A numeric vector of length 2 specifying the time window to restrict the fixations in the input scanpaths (default is NULL, which considers all fixations).
screensize	A numeric vector of length 2 specifying the dimensions of the screen (e.g., c(1000, 1000)). Required for the "multimatch" method.
...	Additional arguments passed to the similarity computation method.

Value

A numeric value representing the similarity between the two input scanpaths.
