NAME
ts - time series analysis
SYNOPSIS
ts [-aeps] [-b base] [-c lag] [-i interval] [-l length]
[-P style] [-n number] [-w width]
DESCRIPTION
_t_s performs a variety of time series analyses on ordered data read
from the standard input.
OPTIONS
-a requests no axes around plot.
-b base
set the base label of the time series.
-c lag
print (auto)correlation of lags 1:lag. 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.
-e echo the time series (may be useful with the -l option).
-i size
set the interval size for plot labels.
-l length
sets the length of the time series. 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 mean line is used for
the center of the plot.
-P plotnum
Plot type. The default (type 1) plots points as deviations from
the mean. Plot type 2 plots points as lines above the minimum.
A line plot of the range indicating the mean and standard
deviation surround plots.
-s Print summary statistics.
-w width
Plot width (default: 70).
EXAMPLES
Side-by-side plots can compare trends in series of different lengths:
ts -p -w 20 -l 30 < data1 > plot1
ts -p -w 20 -l 30 < data2 > plot2
pr -m plot1 plot2
LIMITS
Use the -L option to determine the program limits.
MISSING VALUES
Missing data values (NA) are counted but not included in the analysis.
