Plotting method for objects inheriting from class "ts"
.
## S3 method for class 'ts': plot(x, y = NULL, plot.type = c("multiple", "single"), xy.labels, xy.lines, panel = lines, nc, yax.flip = FALSE, mar.multi = c(0, 5.1, 0, if(yax.flip) 5.1 else 2.1), oma.multi = c(6, 0, 5, 0), axes = TRUE, ...) ## S3 method for class 'ts': lines(x, ...)
x, y |
time series objects, usually inheriting from class "ts" . |
plot.type |
for multivariate time series, should the series by plotted separately (with a common time axis) or on a single plot? |
xy.labels |
logical, indicating if text() labels
should be used for an x-y plot, or character, supplying a
vector of labels to be used. The default is to label for up to 150
points, and not for more. |
xy.lines |
logical, indicating if lines
should be drawn for an x-y plot. Defaults to the value of
xy.labels if that is logical, otherwise to TRUE . |
panel |
a function(x, col, bg, pch, type, ...) which gives the
action to be carried out in each panel of the display for
plot.type="multiple" . The default is lines . |
nc |
the number of columns to use when type="multiple" .
Defaults to 1 for up to 4 series, otherwise to 2. |
yax.flip |
logical indicating if the y-axis (ticks and numbering)
should flip from side 2 (left) to 4 (right) from series to series
when type="multiple" . |
mar.multi, oma.multi |
the (default) par settings
for plot.type="multiple" . Modify with care! |
axes |
logical indicating if x- and y- axes should be drawn. |
... |
additional graphical arguments, see plot ,
plot.default and par . |
If y
is missing, this function creates a time series
plot, for multivariate series of one of two kinds depending on
plot.type
.
If y
is present, both x
and y
must be univariate,
and a “scatter” plot y ~ x
will be drawn, enhanced by
using text
if xy.labels
is
TRUE
or character
, and lines
if
xy.lines
is TRUE
.
ts
for basic time series construction and access
functionality.
