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

if (FALSE) { # \dontrun{
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))
} # }
