Description Usage Arguments Details Value Examples

This function returns a basic exponential moving average (EMA) of the given vector.

1 |

`vec` |
A numeric vector. |

`n` |
An integer: moving window size, with |

`smFac` |
A number: smoothing factor, with default |

This function makes fairly efficient the computation of EMA, which dubbed as basic
exponential smoothing, the same section of https://en.wikipedia.org/wiki/Exponential_smoothing.
It provides an access to define *smFac* yourself, i.e the smoothing factor,
whose default is *2/(n+1)*.

This function returns a vector whose length is the same as that of *vec*.
