Normalize Eye-Movements to Unit Range

This function normalizes the eye-movements to a unit range based on the specified x and y bounds.

Usage

normalize(x, xbounds, ybounds, ...)

# S3 method for class 'fixation_group'
normalize(x, xbounds, ybounds, ...)

Arguments

x

The input object containing the eye-movements to be normalized.

xbounds

A vector containing the minimum and maximum x bounds for normalization.

ybounds

A vector containing the minimum and maximum y bounds for normalization.

...

Additional arguments to be passed to the normalization method.

Value

An object containing the normalized eye-movements in the unit range.

Examples

fg <- fixation_group(x = c(100, 200, 300), y = c(100, 150, 200),
                     onset = c(0, 200, 400), duration = c(200, 200, 200))
normalize(fg, xbounds = c(0, 400), ybounds = c(0, 300))
#> Fixation group: 3 fixations
#>   x range: [0.2, 0.8]
#>   y range: [0.3, 0.7]
#>   duration range: [200, 200]
#>   onset range: [0, 400]
