R help - Sep 2008 - Problem with misclass function on tree classification

I am working through Tom Minka's lectures on Data Mining and am now on Day
32. The following
is the link:
http://alumni.media.mit.edu/~tpminka/courses/36-350.2001/lectures/day32/
In order to use the functions cited I followed the instructions as follows:

Installed tree package from CRAN mirror (Ca-1)
Downloaded and sourced the file "tree.r"
Downloaded the function "clus1.r"

Having defined a tree "tr, when I write "misclass(tr,x$test)" as
shown in the link
I get an error message that "R does not find the function pred1.tree".

 Is this function included in the tree package? If so it was not in my download.
Is this a bug?
Do you know of a fix?

Thanks for your help
Meir

 <<clus1.r>>  <<tree.r>>
