Detrend {SpecsVerification} | R Documentation

## Auxiliary function for removing trends and mean from observation vector or ensemble matrix.

### Description

Detrend fits a linear function to a time-series of observations or to the time-series of ensemble means of an ensemble matrix. The linear trend is removed, and if option demean is true, the total mean is removed as well.

### Usage

    Detrend(x, demean = TRUE)

### Arguments

`x` | A vector, matrix, or data.frame.
`demean` | logical; if true, the total mean is removed from x

### Value

The function returns an object of the same dimensions as the argument 'x', but with its linear trend and (possibly) its mean removed.

### Examples

     data(eurotempforecast)
     Detrend(ens)
     Detrend(obs, demean=FALSE)
