.SH NAME
ts \- time series analysis
.SH SYNOPSIS
.B ts
[-a] [-b N] [-c N] [-e] [-i N] [-l N] [-n N] [-p] [-P N] [-s] [-w N]
.SH DESCRIPTION
.PP
.I Ts
performs a variety of time series analyses
on data read from the standard input.
A time series is an ordered vector of numbers.
.SH OPTIONS
.TP
.B -a
requests no axes around plot.
.TP
.B -b N
set the base number of the time series to N.
.TP
.B -c N
print (auto)correlation of lags 1:N.
These can be useful for detecting cycles and other trends within the data.
The output for a lag of zero is the correlation of the time series
with the numbers 1 through the length of the time series.
.TP
.B -e
echo the time series (may be useful with \fBl\fP option).
.TP
.B -i N
set the interval size to N.
.TP
.B -l N
sets the length of the time series to N.
This can be useful for summarizing,
or for comparing time series of different lengths.
.TP
.B -n N
number the output lines of plots every N points.
.TP
.B -p
requests a time series plot.
A vertical line of the scaled mean is used for the ``center'' of the plot.
.TP
.B -P N
The type of plot can be specified with an optional plot type number.
The default (type 1) plots points as deviations from the mean.
Plot type 2 plots points as vertical lines.
A line plot of the range indicating the mean ans standard deviation
surround the plots.
.TP
.B -s
requests statistics.
.TP
.B -w N
set the width of the plot to N.
By default, N is 70.
Smaller widths allow side-by-side time series plots (see the pr(1) command).
.SH EXAMPLES
.PP
The following lines allow side-by-side time series plots
that can compare time series trends of different lengths
using the multi-column options of pr.
.nf
	ts -p -w 20 -l 30 < data1 > plot1
	ts -p -w 20 -l 30 < data2 > plot2
	pr -m plot1 plot2
