I have Mathematica versions 6 and 7 installed on my Intel MacBookPro. I am also using the Optica package that currently runs only under version 6. So I am running a notebook with Optica code with Version 6. I load the Histogram package with Needs["Histograms`"] when I start the notebook. Then when I attempt to execute the Histogram function, I get the error message that says it can't find the Histogram symbol. Now, if I go to Help for the Histogram function, the first thing in the Examples section is Needs["Histograms`"], which I execute in the Help notebook. Then the first example in this notebook works correctly, giving a histogram plot of the specified data. But what is bizarre is that the second example fails to plot. When I execute this cell Histogram[RandomReal[{0, 1}, {1000}]], the result is a long list of numbers with Histogram at the head. In the Help notebook, if I do ??Histogram, I get the result: Cell$$4753`Histogram. Why does my notebook not recognize Histogram[] after I load the package? Why does the Help example fail to plot the second example? Is there some interaction between the installation of Mathematica 6 and Mathematica 7 that now prevents Mathematica 6 from recognizing the Histogram package? This behavior is really bizarre.
