plot.ts with multi-plots and Auto-Title – on 1 page

Description

For longer time-series, it is sometimes important to spread the time-series plots over several subplots. p.ts(.) does this both automatically, and under manual control.

Actually, this is a generalization of plot.ts (with different defaults).

Usage

p.ts(x, nrplots = max(1, min(8, n %/% 400)), overlap = nk %/% 16,
     date.x = NULL, do.x.axis = !is.null(date.x), do.x.rug = FALSE,
     ax.format, main.tit = NULL, ylim = NULL, ylab = "", xlab = "Time",
     quiet = FALSE, mgp = c(1.25, .5, 0), ...)

Arguments

x	timeseries (possibly multivariate) or numeric vector.
nrplots	number of sub-plots. Default: in {1..8}, approximately n/400 if possible.
overlap	by how much should subsequent plots overlap. Defaults to about 1/16 of sub-length on each side.
date.x	a time “vector” of the same length as x and coercable to class "POSIXct" (see DateTimeClasses).
do.x.axis	logical specifying if an x axis should be drawn (i.e., tick marks and labels).
do.x.rug	logical specifying if rug of date.x values should drawn along the x axis.
ax.format	when do.x.axis is true, specify the format to be used in the call to axis.POSIXct.
main.tit	Main title (over all plots). Defaults to name of x.
ylim	numeric(2) or NULL; if the former, specifying the y-range for the plots. Defaults to a common pretty range.
ylab, xlab	labels for y- and x-axis respectively, see description in plot.default.
quiet	logical; if TRUE, there's no reporting on each subplot.
mgp	numeric(3) to be passed to mult.fig(), see par(mgp = .).
...	further graphic parameters for each plot.ts(..).

Side Effects

A page of nrplots subplots is drawn on the current graphics device.

Examples

stopifnot(require(stats))
## stopifnot(require(datasets))

data(sunspots)
p.ts(sunspots, nr=1) # == usual  plot.ts(..)
p.ts(sunspots)
p.ts(sunspots, nr=3, col=2)

data(EuStockMarkets)
p.ts(EuStockMarkets[,"SMI"])
## multivariate :
p.ts(log10(EuStockMarkets), col = 2:5)

## with Date - x-axis (dense random dates):
set.seed(12)
x <- as.Date("2000-02-29") + cumsum(1+ rpois(1000, lambda= 2.5))
z <- cumsum(.1 + 2*rt(1000, df=3))
p.ts(z, 4, date.x = x)
p.ts(z, 6, date.x = x, ax.format = "%b %Y", do.x.rug = TRUE)
