This command displays a summary of the character values exhibited by the specified set of taxa, for the specified set of characters. The output line labelled "U/I/Recorded" gives, for each character, the numbers of taxa for which the character is unknown, inapplicable, or recorded. Multistate and integer numeric values are summarized as a "distribution of values". Each value is followed by the number (in parentheses) of taxa which exhibit the value. If this number is the same for consecutive values of a character, the values are expressed as a range; note that this does not imply that the range occurs as such in any of the members of the set. Real numeric values are summarized as a "mean" and "standard deviation". The standard deviation is calculated from the within-taxon means, that is, the variation within taxa is not included. If difficulties arise with interpretation of the output, comparison with DESCRIBE output may be helpful. See also OUTPUT SUMMARY, Keywords.
Syntax of command line: SUMMARY (t1 t2 ...) c1 c2 ...
where t1, t2 ... are taxon numbers, ranges or keywords, and c1, c2 ... are character numbers, ranges or keywords. If there is only one taxon number, range or keyword, the parentheses may be omitted.
