y1, y2 
Regular time series, time series matrices or ordinary
vectors, dataframes or matrices with values corresponding to regular
time intervals. Corresponding axes are on the left (for 
names1, names2 
Names for time series used for legend. 
startP 
Start time of plot. 
upf 
Number of time units plottet per figure. 
fpp 
Number of figures per page (screen). 
overlap 
Length of time series on the right end of the figures which is identical with the left start of the next figure. 
x.at 
Time points at which long ticks on xaxis and annotations are set. 
x.ann 
Time annotations (character vector) for long ticks on xaxis 
x.tick 
Time points at which short ticks are set on xaxis. If Null, no short ticks are set. 
y1.at, y1.ann, y1.tick, y2.at, y2.ann, y2.tick 
Arguments starting with 'y1' ('y2') correspond to arguments for left (right) axis. For details see arguments for xaxis. 
nx.ann, ny.ann 
Approximate number of annotations on x and yaxes, respectively 
cex.ann 
The magnification to be used for axis annotation relative to the current setting of cex. 
xlab 
Label for xaxis. 
y1lab, y2lab 
Labels for yaxes on the left and on the right end of the figure. 
las 
Cf. 
col.y1, col.y2 
Colors for left and right axis respectively. 
cex.lab 
cex of labels. 
y1lim, y2lim 
Limits for left and right axis respectively. 
lty1, lty2 
Vector of line types for each time series, possibly recycled. 
lwd1, lwd2 
Vector of line widths for each time series, possibly recycled. 
col1, col2 
Vector of color for each time series, possibly recycled. 
leg 
Logical. When TRUE, legend is drawn. 
y1nam.leg, y2nam.leg 
Name of y1 and y2axis in legend. 
ncol.leg 
Number of columns in legend. 
cex.leg 
cex for legend. 
h1, h2 
Vector of ypositions of horizontal lines in the coordinate systems represented by the left and the right axis respectively. 
col.h1, col.h2 
Vector of colors for horizontal lines. 
main 
Title of plot. 
cex.main 
cex of title. 
automain 
Logical. When 
mgp, mar, oma 
Cf. 
xpd 
Define whether data points are clipped to the plot region
(=FALSE) or not (=TRUE). Horizontal lines, defined by 
cex 
Cf. 
type1, type2 
For plotting lines or
points. Cf. 
pch1, pch2, cex.pt1, cex.pt2 
Plotting symbols and there sizes when 'type1' or 'type2' = "p" 
slide 
Logical. When 
each.fig 
For 
filename

extension 
The extension is defined automatically on windows systems and must be defined manually on the other systems. 
filetype 
On Windows:
The type of plot, Windows metafile, PNG, JPEG,
BMP (Windows bitmap format), TIFF, PostScript or PDF.
Defaults to Windows meta file,

For longer timeseries, it is sometimes important to spread several
timeseries plots over several subplots or even over several pages
with several subplots in each. Moreover, these series have often
different ranges, frequencies and start times. There is sometimes also
the need of a more flexible annotation of axes than plot.ts
provides. longtsPlot
provides the user with all these features
for one or two matrices or regular time series (time series matrices).
One or more pages of time series plots are drawn on the current graphic device and, optionally, saved in one or more files.
