Convert time-series-like to data.frame

Description

Convert time-series-like to data.frame

Usage

## S3 method for class 'ts'
fortify(
  model,
  data = NULL,
  columns = NULL,
  is.date = NULL,
  index.name = "Index",
  data.name = "Data",
  scale = FALSE,
  melt = FALSE,
  ...
)

Arguments

model	time-series-like instance
data	original dataset, if needed
columns	character vector specifies target column name(s)
is.date	logical frag indicates whether the stats::ts is date or not If not provided, regard the input as date when the frequency is 4 or 12
index.name	specify column name for time series index
data.name	specify column name for univariate time series data. Ignored in multivariate time series.
scale	logical flag indicating whether to perform scaling each timeseries
melt	logical flag indicating whether to melt each timeseries as variable
...	other arguments passed to methods

Value

data.frame

Examples

## Not run: 
fortify(AirPassengers)
fortify(timeSeries::as.timeSeries(AirPassengers))
fortify(tseries::irts(cumsum(rexp(10, rate = 0.1)), matrix(rnorm(20), ncol=2)))
fortify(stats::stl(UKgas, s.window = 'periodic'))
fortify(stats::decompose(UKgas))

## End(Not run)
