Did you say:
library("tree")
at the top of your script?

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?
