Plotting Time-Series Objects

Plotting method for objects inheriting from class "ts".

Keywords
hplot, ts
Usage
"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, ...)
"lines"(x, ...)
Arguments
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.
Details

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.
