PlotTimeSeries: Plot Temporal Data

Description

Draws a time-series plot with points and connecting lines.

Usage

PlotTimeSeries(x, y = NULL, xlim = NULL, ylim = NULL, ylab = NULL,
               tgap = NULL, width = 7, cex.pts = 1,
               pointsize = 12, fmt = NULL, axis.side = 1:2,
               minor.ticks = FALSE, ticks.inside = FALSE,
               rm.pnt.line = FALSE)

Arguments

x

POSIXct; a vector specifying x values.

y

numeric; a vector specifying y values.

xlim

POSIXct; the x limits (x1,x2) of the plot.

ylim

numeric; the y limits (y1,y2) of the plot.

ylab

character; the label for the y axis.

tgap

numeric; time gap exceedance level in seconds.

width

numeric; the width of the plotting window canvas in inches.

cex.pts

numeric; the amount by which point symbols should be magnified relative to the default.

pointsize

integer; the point size of plotted text.

fmt

character; date-time format for x axis tickmark labels, see strptime.

axis.side

integer; the side of the plot the axis is to be drawn on. The axis is placed as follows: 1 = below, 2 = left, 3 = above and 4 = right.

minor.ticks

logical; if TRUE minor tickmarks are added to the plot; its default is FALSE.

ticks.inside

logical; if TRUE tickmarks are placed inside the plot region; its default is FALSE.

rm.pnt.line

logical; if TRUE the line boundary on point symbols is not drawn; its default is FALSE.

Details

Line segments will not be drawn where time differences between consecutive points are greater than tgap.
