sample_density: sample_density

In bbuchsbaum/eyesim: analysis of eye-movement data

sample_density

Description

Sample a smooth fixation density map with a set of discrete fixations.

Usage

sample_density(x, fix, ...)

Arguments

x	An object representing the smooth fixation density map to be sampled.
fix	A data frame containing the discrete fixations used for sampling the density map.
...	Additional arguments passed on to the method.

Details

This function samples a given smooth fixation density map with a set of discrete fixations to estimate the density at the locations of those fixations.

Value

A data frame with columns 'z' (density estimates at fixation locations) and 'time' (onset time of fixations).

See Also
