signal_shift.Rd

Shifts the x scale by a given value.

Usage

signal_shift(x, y, lag, ...)

# S4 method for class 'numeric,numeric'
signal_shift(x, y, lag)

# S4 method for class 'ANY,missing'
signal_shift(x, lag)

Arguments

x, y

A numeric vector. If y is missing, an attempt is made to interpret x in a suitable way (see grDevices::xy.coords()).

lag

A numeric vector specifying the offset.

Examples

## X-ray diffraction
data("XRD")

## Plot spectrum
plot(XRD, type = "l", xlab = expression(2*theta), ylab = "Count")

## Shift by one degree
XRD_offset <- signal_shift(XRD, lag = 1)
lines(XRD_offset, type = "l", col = "red")
