R: Frechet distance

FrechetDistance {TSdist} | R Documentation

## Frechet distance

### Description

Computes the Frechet distance between two numerical trajectories.

### Usage

    FrechetDistance(x, y, tx, ty, ...)

### Arguments

`x` | Numeric vector containing the first time series.
`y` | Numeric vector containing the second time series.
`tx` | If not constant, a numeric vector that specifies the sampling index of series `x`.
`ty` | If not constant, a numeric vector that specifies the sampling index of series `y`.
`...` | Additional parameters for the function. See `distFrechet` for more information.

### Details

This is essentially a wrapper for the `distFrechet` function of package longitudinalData. As such, all the functionalities of the `distFrechet` function are also available when using this function.

### Value

`d` | The computed distance between the pair of series.

    # The objects example.serie3 and example.series4 are two
    # numeric series of length 100 and 120, respectively.

    data(example.series4)

    # For information on their generation and shape see
    # help page of example.series.

    help(example.series)

    # Calculate the distance based on wavelet feature extraction between the series.
