Description Usage Arguments Value See Also Examples

Returns suitably lagged and iterated differences using arbitrary difference functions.

1 |

`x` |
a numeric vector or matrix containing the values to be differenced. |

`lag` |
an integer indicating which lag to use. |

`differences` |
an integer indicating the order of the difference. |

`FUN` |
A distance function that accepts two parameters |

`...` |
further arguments to be passed to or from methods. |

If x is a vector of length `n`

and `differences = 1`

, then
the computed result is equal to the successive differences
`FUN(x[(1+lag):n], x[1:(n-lag)])`

.

If `difference`

is larger than one this algorithm is applied
recursively to `x`

. Note that the returned value is a vector which is
shorter than `x`

.

If `x`

is a matrix then the difference operations are carried out on each
column separately.
