Data Transformation: Linear Trend of Zoo Time Series

Fits a linear model on each column of a zoo object using time as a predictor, and predicts the outcome.

Usage

f_trend_linear(x = NULL, center = TRUE, ...)

Arguments

x

(required, zoo object) Zoo time series object to transform.

center

(required, logical) If TRUE, the output is centered at zero. If FALSE, it is centered at the data mean. Default: TRUE

...

(optional, additional arguments) Ignored in this function.

Value

zoo object
