functions in std.i - h


     returns 1 if FILE has history records, 0 if it does not.  
interpreted function, defined at i0/std.i   line 2525  

             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.  
       help, set_path  
     prints the documentation for the set_path function.  
     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.  
       help, dbexit  
     for help on debug mode.  If your prompt is "dbug>" instead of  
     ">", dbexit will return you to normal mode.  
     to quit Yorick.

          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.)
