Examples

## Not run: 
library(intubate)
library(magrittr)
library(forecast)

## ntbt_tslm: Fit a linear model with time series components
dta <- data.frame(y <- ts(rnorm(120,0,3) + 1:120 + 20*sin(2*pi*(1:120)/12), frequency=12))

## Original function to interface
tslm(y ~ trend + season, data = dta)

## The interface puts data as first parameter
ntbt_tslm(dta, y ~ trend + season)

## so it can be used easily in a pipeline.
dta %>%
  ntbt_tslm(y ~ trend + season)

## End(Not run)
