[R-marketing-bugs] RF code

[Chris Chapman]

You are right, somehow that line was omitted from the book (it's in the .R
file, however). Specifically, it should read:

seg.rf.class <- predict(seg.rf, seg.df.test)     # <=== the line to add

library(cluster)
clusplot(seg.df.test[, -7], seg.rf.class, color=TRUE, shade=TRUE,
         labels=4, lines=0, main="Random Forest classification, holdout
data")

Thanks for the note! I'll add it to the Errata (as confirmed fix #1),
