| help 
 | 
             help, topic  
          or help  
 
     Prints DOCUMENT comment from include file in which the variable  
     TOPIC was defined, followed by the line number and filename.  
     By opening the file with a text editor, you may be able to find  
     out more, especially if no DOCUMENT comment was found.  
     Examples:  
       help, set_path  
     prints the documentation for the set_path function.  
       help  
     prints the DOCUMENT comment you are reading.  
     This copy of Yorick was launched from the directory:  
     **** Y_LAUNCH (computed at runtime) ****  
     Yorick's "site directory" at this site is:  
     **** Y_SITE (computed at runtime) ****  
     You can find out a great deal more about Yorick by browsing  
     through these directories.  Begin with the site directory,  
     and pay careful attention to the subdirectories doc/ (which  
     contains documentation relating to Yorick), and i/ and  
     contrib/ (which contain many examples of Yorick programs).  
     Look for files called README (or something similar) in any  
     of these directories -- they are intended to assist browsers.  
     The site directory itself contains std.i and graph.i, which  
     are worth reading.  
     Type:  
       help, dbexit  
     for help on debug mode.  If your prompt is "dbug>" instead of  
     ">", dbexit will return you to normal mode.  
     Type:  
       quit  
     to quit Yorick.

| histogram 
 | 
             histogram(list)  
          or histogram(list, weight)  
 
     returns an array hist which counts the number of occurrences of each  
     element of the input index LIST, which must consist of positive  
     integers (1-origin index values into the result array):  
          histogram(list)(i) = number of occurrences of i in LIST  
     A second argument WEIGHT must have the same shape as LIST; the result  
     will be the sum of WEIGHT:  
          histogram(list)(i) = sum of all WEIGHT(j) where LIST(j)==i  
     The result of the single argument call will be of type long; the  
     result of the two argument call will be of type double (WEIGHT is  
     promoted to that type).  The input argument(s) may have any number  
     of dimensions; the result is always 1-D.  
   KEYWORD: top=max_list_value  
     By default, the length of the result is max(LIST).  You may  
     specify that the result have a larger length by means of the TOP  
     keyword.  (Elements beyond max(LIST) will be 0, of course.)
