R Documentation

Draw a simple time series plot

Description

Draws a plot of a given inzightts (inz_ts) object with the trend superimposed.

Usage

## S3 method for class 'inz_ts'
plot(
  x,
  var = NULL,
  xlab = NULL,
  ylab = NULL,
  title = NULL,
  xlim = NULL,
  aspect = NULL,
  compare = TRUE,
  pal = NULL,
  smoother = TRUE,
  sm_model = "stl",
  t = 0,
  mult_fit = FALSE,
  emphasise = NULL,
  non_emph_opacity = 0.2,
  show_iso_obs = TRUE,
  iso_obs_size = 1,
  ...
)

Arguments

`x`	An `inzightts` (`inz_ts`) object representing the time series.
`var`	A character vector specifying the variable(s) to be plotted, or set to `NULL`.
`xlab`	A title for the x-axis of the plot.
`ylab`	A title for the y-axis of the plot.
`title`	A title for the graph.
`xlim`	Axis limits, specified as dates or years.
`aspect`	The aspect ratio of the plot; it will be about `aspect` times wider than it is high.
`compare`	Logical; set to `TRUE` to plot the key levels in a single plot.
`pal`	(Only if a categorical variable is passed to `var`): The colour palette for the categorical plot. The palette vector should be in the same order per the rows of `tsibble::key_data(x)`.
`smoother`	Logical; if `TRUE`, the smoother will be drawn.
`sm_model`	The smoothing method to be used.
`t`	The smoothing parameter (between 0 and 100).
`mult_fit`	Logical; set to `TRUE` for a multiplicative model, or `FALSE` for the default additive model.
`emphasise`	Integer vector to specify the key level(s) to focus in the plot. The integer maps to the specific key level(s) corresponding to the ith row of `tsibble::key_data(x)`.
`non_emph_opacity`	Numeric. If `(0, 1]`, this argument determines the opacity of the series other than the focused one(s) (to highlight the focused series). If `non_emph_opacity = 0`, the plot draws the focused series in its own scales.
`show_iso_obs`	Logical; set to `TRUE` to plot isolated observations between time series gaps (if any).
`iso_obs_size`	Numeric; scaling the size of isolated observations, if `show_iso_obs = TRUE` and they exist.
`...`	Additional arguments (ignored).

Value

A time series plot (constructed with ggplot2) is returned, which can be added to if desired.

Examples

t <- inzightts(visitorsQ, var = c(2, 4))

## Not run: 
plot(t)
plot(t, var = names(t)[-1])
plot(t, var = "Japan")
plot(t, mult_fit = TRUE)

## End(Not run)
