Function to add directly to the plot the ARIMA model used in the pre-adjustment process of the seasonal adjustment.
Set of aesthetic mappings created by aes() or
aes_(). If specified and
inherit.aes = TRUE (the
default), it is combined with the default mapping at the top level of the
plot. You must supply
mapping if there is no plot mapping.
data.frame that contains the data used for the seasonal adjustment.
The statistical transformation to use on the data for this layer, as a string.
Position adjustment, either as a string, or the result of a call to a position adjustment function.
Other arguments passed on to layer(). These are
often aesthetics, used to set an aesthetic to a fixed value, like
colour = "red" or
size = 3.
the method used for the seasonal adjustment.
"x13" (by default) for the X-13ARIMA method and
"tramoseats" for TRAMO-SEATS.
the frequency of the time series. By default (
frequency = NULL),
the frequency is computed automatically.
boolean indicating if a message is printed with the frequency used.
position of the text of the ARIMA model. By default, the first position of the
data is used.
logical. Should this layer be included in the legends?
NA, the default, includes if any aesthetics are mapped.
FALSE never includes, and
TRUE always includes.
It can also be a named logical vector to finely select the aesthetics to
FALSE, overrides the default aesthetics,
rather than combining with them.
With the parameter
geom = "text", the ARIMA model used in the pre-adjustment process of the seasonal adjustment are directly added to the plot. With
geom = "label" a rectangle is drawn behind the ARIMA model, making it easier to read.
