Consolidate pupil data according to different heuristics
Source:R/consolidate_signal.R
consolidate_signal.RdMostly used, e.g., when pupil data is available for both eyes and one needs a single variable. Results are weighted by vectors of signal validity as provided by the eye-trackers. If absent, that all signals is valid is assumed.
Usage
consolidate_signal(
s1,
s2,
v1,
v2,
strategy = c("conservative", "liberal", "pick_best"),
plausible = NULL
)Arguments
- s1
A vector with the first signal.
- s2
A vector with the second signal.
- v1
A vector with the weights for the first signal.
- v2
A vector with the weights for the second signal.
- strategy
A strategy for mixing the two signals. Conservative takes the mean only when both signals are valid. Liberal additionally take one valid signal even when the other is not valid. Pick_best chooses the best overall signal (valid more often) and disregard the other when only one of the two is valid.
- plausible
A vector of length 2 defining the range of plausible values for pupil size. If provided, values outside this range are set to NA.
