seqplot

Time series plot.

Description

Time series plot.

Usage

seqplot(xts, ...)

## Default S3 method:
seqplot(xts,
        pch.seq=letters,
        groups=as.numeric(cycle(xts)),
        a=NULL, b=NULL, h=NULL, v=NULL,
        ylab=deparse(substitute(xts)),
        xlab="Time",
        lwd=1, lty=c(1,3),
        type="b",
        col=trellis.par.get("superpose.symbol")$col,
        col.line="gray60",
        ...)







## S3 method for class 'ts'
seqplot(xts, pch.seq=letters, groups=as.numeric(cycle(xts)),
        x.at=pretty(time(xts)[groups==min(groups)]),
        x.labels,
        ylab=deparse(substitute(xts)),
        ...)

Arguments

`xts`	Time series
`pch.seq`	sequence of `pch` characters for use with the time series. The characters repeat over the cycle of the series.
`groups`	Numeric vector used to choose the plotting characters over cycles.
`a, b, h, v`	Arguments to `panel.abline`.
`ylab, xlab, lwd, lty, type`	standard trellis arguments.
`x.at, x.labels`	shortcut for `scales=list(x=list(at=x.at, labels=x.labels))`
`col`	Color of dots in sequence plot. The default is to make the choose a number of colors to match the frequency of the time series `xts`.
`col.line`	Color of connecting lines. The default is `"gray60"`.
`...`	Additional arguments to `xyplot`.
