[R] Two way joining vs heatmap

[Schalk Heunis]

Hi

STATISTICA has a function called "Two-way joining" (see
http://www.statsoft.com/TEXTBOOK/stcluan.html#twotwo) and the
reference material states that this is based on the method as
published by Hartigan (found this paper:
http://www.jstor.org/pss/2284710 through wikipedia).

What is the relationship (if any) between the "heatmap" function in R
and this technique? Is there an alternative function to use?

Thanks for the help!
