_avoid_ partial matching, not accomplish it. Subset is a _much_ better
way of doing what I was trying to do.

Dear Friends,
How can I extract the coordinates used in the plot?
They are not made available. You can get them as follows:
x - rbind(cbind(rnorm(10, 0, 0.5), rnorm(10, 0, 0.5)),
cbind(rnorm(15, 5, 0.5), rnorm(15, 5, 0.5)))
pp - pam(x, 2)
## The coordinates are in obj$scores

Hi,
I wonder what kind of interest there is on Test Driven Development (TDD) in R.
Test Driven Development consists of writing the test before the function, and
iteratively build the function until it passes the test.
Python and Ruby (specially Ruby) have very strong test-oriented cultures.
