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.

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.
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.)
