statstable - compute basic stats about the columns of a table.

SYNOPSYS

    `statstable` < *table*

    `meantable`  < *table*
    `medtable`   < *table*
    `mintable`   < *table*
    `maxtable`   < *table*
    `rmstable`   < *table*
    `stdtable`   < *table*
    `sumtable`   < *table*
    `tottable`   < *table*

DESCRIPTION

statstable read the input file from the standard input and outputs a table of basic statistics on the standard output. It computes the sum, min, max, mean, median, standard devaition and range of a column.

The output is a table of computed values one column for each column in the input table and an extra column named “Stat” to identify the statistic in each row prepended to the table.

Thses short scripts call statstable to compute a single statistic.
