NAME
     ts - time series analysis

SYNOPSIS
     ts [-a] [-b N] [-c N] [-e] [-i N] [-l N] [-n N] [-p] [-P N]
     [-s] [-w N]

DESCRIPTION
     _▶08◀T_▶08◀s performs a variety of time series analyses on data read
     from the standard input.  A time series is an ordered vector
     of numbers.

OPTIONS
     -a   requests no axes around plot.

     -b N set the base number of the time series to N.

     -c N print (auto)correlation of lags 1:N.  These can be use-
          ful 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.

     -e   echo the time series (may be useful with l option).

     -i N set the interval size to N.

     -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.

     -n N number the output lines of plots every N points.

     -p   requests a time series plot.  A vertical line of the
          scaled mean is used for the ``center'' of the plot.

     -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.

     -s   requests statistics.

     -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).

EXAMPLES
     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.
