Source: R/filters.R
filterSignals.Rd

Applies a moving average filter along the first dimension (time axis) of the default assay.

Usage

filterSignals(x, window = 5L, na.rm = FALSE, output_assay = "filtered")

Arguments

x

A PhysioExperiment object.

window

Integer window length for the moving average.

na.rm

Logical. If TRUE, NA values are ignored in the filter computation.

output_assay

Name for the output assay. Default is "filtered".

Value

A PhysioExperiment object with a new assay named output_assay containing the moving-average-filtered data. Dimensions match the input assay. Edge values where the full window cannot be applied are set to NA.
