signal_fill: Fill NA-gaps of a signal

Description

This function performs linear interpolation of NA values.

Usage

signal_fill(data)

Value

eseis object, numeric vector or list of objects, interpolated data set(s).

Arguments

data

eseis object, numeric vector or list of objects, data set to be processed.

Author

Details

Note that the procedure will contaminate the signal by artefacts as increasingly larger data gaps are filled with interpolated values.

Examples

## create synthetic data set and add NA-gaps
x <- eseis::signal_detrend(data = runif(1000))
x_gap <- x
x_gap[100:102] <- NA
x_gap[500:530] <- NA

## fill gaps
y <- signal_fill(data = x_gap)

## filter both data sets
x <- signal_filter(data = x, f = c(1, 3), dt = 1/200)
y <- signal_filter(data = y, f = c(1, 3), dt = 1/200)

## plot both data sets
plot(y, type = "l", col = "grey", lwd = 3)
lines(x, col = "red")
