R: Lagged Quotients

Quot {DescTools} | R Documentation

## Lagged Quotients

### Description

Returns suitably lagged and iterated quotients

### Usage

      Quot(x, lag = 1, quotients = 1, ...)

### Arguments

`x` | a numeric vector or matrix containing the values to be used for calculating the quotients.
`lag` | an integer indicating which lag to use.
`quotients` | an integer indicating the order of the quotient.
`...` | further arguments to be passed to or from methods.

### Details

`NA`'s propagate.

### Value

If `x` is a vector of length `n` and `quotients = 1`, then the computed result is equal to the successive quotients `x[(1+lag):n] - x[1:(n-lag)]`.

If `quotients` 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 division operations are carried out on each column separately.
