PAIR(1)

NAME
pair - paired data points analysis and plots

SYNOPSIS
pair [-fps] [-h height] [-w width] [-c char] [-x xname] [-y yname]
    [-t top] [-b bottom] [-l left] [-r right]

DESCRIPTION
pair analyzes paired data by providing summary statistics and scattergrams. pair reads pairs of points (two points per line) from the standard input and, without options, provides statistics on the first variable (X), the second (Y), and their difference. If only one datum is on each line, then pair will supply the datum number (1 to N) as the first variable and use the datum as the second.

OPTIONS
[b bottom] minimum Y value at the bottom of the plot (default: from data). [c char] plotting character (default: frequency counts). [f] do not print frame around plot (default: print frame). [h height] set height of the plot to height lines. [l left] minimum X value at the left of the plot (default: from data). [p] print bivariate plot. [r right] maximum X value at the right of the plot (default: from data). [s] requests summary statistics. [t top] maximum Y value at the top of the plot (default: from data). [w width] set width of the plot to width characters. [x name] name of the first variable (default: "Column 1"). [y name] name of the second variable (default: "Column 2").

EXAMPLES
pair -p -h 10 -w 20	# 10 high, 20 wide plot
abut a b | pair -x a -y b	# compare two single column files

LIMITS
Use the -L option to determine the program limits.

MISSING VALUES
Cases with missing data values (NA) are counted but not included in the analysis.
