Plotting regarima, decomposition or final results of a SA

Plotting methods for the S3 class objects around the seasonal adjustment: "regarima" for RegARIMA,"decomposition_X11" and "decomposition_SEATS" for the decomposition with X13 and TRAMO-SEATS, "final" for the final SA results and "SA" for the entire seasonal adjustment object. The function plot.SA just calls the function plot.final.

Usage

# S3 method for class 'regarima'
plot(
  x,
  which = 1:6,
  caption = list("Residuals", "Histogram of residuals", "Normal Q-Q", "ACF of residuals",
    "PACF of residuals", "Decomposition", list("Y linearised", "Calendar effects",
    "Outliers effects"))[sort(which)],
  ask = prod(par("mfcol")) < length(which) && dev.interactive(),
  ...
)

# S3 method for class 'decomposition_X11'
plot(x, first_date, last_date, caption = "S-I ratio", ylim, ...)

# S3 method for class 'decomposition_SEATS'
plot(x, first_date, last_date, caption = "S-I ratio", ylim, ...)

# S3 method for class 'final'
plot(
  x,
  first_date,
  last_date,
  forecast = TRUE,
  type_chart = c("sa-trend", "cal-seas-irr"),
  caption = c(`sa-trend` = "Y, Sa, trend", `cal-seas-irr` =
    "Cal., sea., irr.")[type_chart],
  ask = length(type_chart) > 1 && dev.interactive(),
  ylim,
  ...
)

# S3 method for class 'SA'
plot(x, ...)

Arguments

x

the object to plot

which

a numeric vector specifying which graphs should be plotted: (1) "Residuals", (2) "Histogram of residuals", (3) "Normal Q-Q", (4) "ACF of residuals", (5) "PACF of residuals", (6) "Decomposition", (7) "Decomposition - zoom"

caption

a string containing the graph title

ask

a Boolean. If TRUE, the user will be prompted before a new graphical page is started.

...

other parameters

first_date

the plot starting date. If missing, the plot starts at the beginning of the time-series.

last_date

the end date of the plot. If missing, the plot ends at the end of the time-series (eventually, including forecast).

ylim

the y limits of the plot.

forecast

a Boolean indicating if forecasts should be included in the plot. If TRUE, the forecast is plotted.

type_chart

a string indicating which type of chart to plot

Examples

# \donttest{
myseries <- ipi_c_eu[, "FR"]
mysa <- x13(myseries, spec = c("RSA5c"))
  # RegArima
plot(mysa$regarima) # 6 graphics are plotted by default






# To plot only one graphic (here, the residuals) and change the title:
plot(mysa$regarima, which = 1, caption = "Plot of residuals")

plot(mysa$regarima, which = 7)


  # Decomposition
plot(mysa$decomposition) # To plot the S-I ratio

plot(mysa$decomposition, first_date = c(2010, 1)) # To start the plot in January 2010


  # Final
plot(mysa$final) # 2 graphics are plotted by default


# To only plot one graphic (here the raw data, the seasonally adjusted data and the trend),
# To change the last date and the title
plot(mysa$final, last_date = c(2000, 1),
     caption = "Results", type_chart = "sa-trend")

# }
