[R-marketing-bugs] error chap 11. Mclust()

[Chris Chapman]

It looks like the recent update of Mclust to version 5 has caused this to
fail.

If you are using a Mac or Linux and can compile packages from source, then
you could downgrade Mclust to the previous version 4.4 as follows:

old.mc <- "
https://cran.r-project.org/src/contrib/Archive/mclust/mclust_4.4.tar.gz"

install.packages(old.mc, repos=NULL, type="source")

If you use Windows you  might be able to find a compiled ZIP for mclust 4.4
on the web somewhere.


After that, everything works as expected:

> seg.mc <- Mclust(seg.df.num)
> summary(seg.mc)
----------------------------------------------------
Gaussian finite mixture model fitted by EM algorithm
----------------------------------------------------

Mclust EEV (ellipsoidal, equal volume and shape) model with 3 components:

 log.likelihood   n df       BIC       ICL
      -5256.222 300 71 -10917.41 -10955.48

Clustering table:
  1   2   3
111 115  74


Hopefully the Mclust developers will fix this. I'll email them and ask!
Thanks for the report, and I hope you're enjoying the book,

-- Chris
