Usage

replaceNA(
  x,
  method = "interpolate",
  input_assay = NULL,
  output_assay = "na_handled"
)

Arguments

x

A PhysioExperiment object.

method

Method for handling NA (see handleNA).

input_assay

Input assay name. If NULL, uses default assay.

output_assay

Output assay name. Default is "na_handled".

Value

Examples

pe <- PhysioExperiment(
  assays = list(raw = matrix(c(1, NA, 3, NA, 5, 6), nrow = 3)),
  samplingRate = 100
)

# Interpolate NA values
pe <- replaceNA(pe, method = "interpolate")
