The function calculates a local maximum of the vector `x`

surrounded by at least `n.points`

lower numbers.

1 | ```
localmax(x, n.points=2)
``` |

`x` |
a vector of numbers. |

`n.points` |
a minimum number of lower values to determine the local maximum. Default is two points. |

The function calculates a local maximum of the vector `x`

, i.e. the highest value of the vector `x`

surrounded by at least `n`

lower numbers. The concept of the local maximum applied to ERP analysis is taken from Luck (2005).

The local maximum of the vector `x`

is returned.
