xyplot methods for time series objects (of class "zoo",
"its", or "tis").
# S3 method for zoo
xyplot(x, data, ...)# S3 method for zoo
llines(x, y = NULL, ...)
# S3 method for zoo
lpoints(x, y = NULL, ...)
# S3 method for zoo
ltext(x, y = NULL, ...)
panel.segments.zoo(x0, x1, ...)
panel.rect.zoo(x0, x1, ...)
panel.polygon.zoo(x, ...)
Invisibly returns a "trellis" class object. Printing this
object using print will display it.
time series object of class "zoo", "its" or
"tis". For panel.plot.default it should be a numeric
vector.
numeric vector or matrix.
not used.
arguments are passed to xyplot.ts, and may be
passed through to xyplot and
panel.xyplot.
Some of the commonly used arguments are:
screensfactor (or coerced to factor) whose levels specify which
graph each series is to be plotted in. screens = c(1, 2, 1)
would plot series 1, 2 and 3 in graphs 1, 2 and 1. This also defines
the strip text in multi-panel plots.
scalesthe default is set so that all
series have the "same" X axis but "free" Y axis.
See xyplot in the lattice package for more
information on scales.
layoutnumeric vector of length 2 specifying number of columns
and rows in the plot, see xyplot for more details.
The default is to fill columns with up to 6 rows.
xlabcharacter string used as the X axis label.
ylabcharacter string used as the Y axis label. If there
are multiple panels it may be a character vector the same length
as the number of panels, but NOTE in this case the vector
should be reversed OR the argument as.table set to
FALSE.
lty, lwd, pch, type, colgraphical arguments passed to panel.xyplot.
These arguments can also be vectors or (named) lists, see details
for more information.
xyplot.zoo plots a "zoo", "its" or "tis"
object using xyplot.ts from
lattice. Series of other classes are coerced to "zoo"
first.
The handling of several graphical parameters is more
flexible for multivariate series. These parameters can be
vectors of the same length as the number of series plotted or
are recycled if shorter. They can also be (partially) named list, e.g.,
list(A = c(1,2), c(3,4)) in which c(3, 4) is the
default value and c(1, 2) the value only for series A.
The screens argument can be specified in a similar way.
Note that since zoo 1.6-3 plot.panel.default and
plot.panel.custom are no longer necessary, as normal panel
functions (panel.xyplot by default) will work.
Similarly, there are now methods for the generic lattice drawing
functions llines,
lpoints, and
ltext. These can also be called as
panel.lines, panel.points, and panel.text,
respectively. The old interfaces (panel.lines.zoo,
panel.points.zoo, and panel.text.zoo), will be
removed in future versions. panel.polygon.zoo may also be
removed.
