Indeed, this is just one instance of a general oversight in the Documentation Center -- neglecting to say explicitly that you must load the package in which a function identified as being from a package is defined. Thus if you go to the Histogram reference page, at the top you'll see in gray, "HISTOGRAMS PACKAGE SYMBOL", but nowhere on the page does it show the expression to load the package. And that gray legend at the top is easy to miss. Moreover, if you follow the "More about" link at the bottom of the page to go to the Histograms Package page, you'll just find a list of the packages two functions (along with some further "More about" links), but still nothing about loading the package! In Mathematica 5.2, the page for a package typically showed near its start the expression needed to load it. (In the case of function Histogram, this was the Help Browser page on Graphics`Graphics`.)

This stuff should be in the help files. -- Murray Eisenberg murray at math.umass.edu Mathematics & Statistics Dept.
