R: Transform time according to a given warping function

warp.time {ptw} | R Documentation

## Transform time according to a given warping function

### Description

Warp time points according to a warping function.

### Usage

    warp.time(tp, coef)

### Arguments

`tp` | A vector of time points, not necessarily equidistant.
`coef` | The coefficients of the parametric time warping function: the first coefficient is the constant shift, the second the linear stretch etcetera.

### Value

The function returns a vector of warped time points.

### Examples

    time <- 1:100
    ## simple shift and compression
