The installer (unlike, say, the 2.12.0 RC version) seems to have been

Thank you for the help! I was misunderstanding how 'outer' produced its grid

How do I reduce the size of those points?

There is a danger in applying logical tests of equality to floating
point numbers. It may be safer to use all.equal or zapsmall in the
construction of your tests.
all.equal( (2^(0.5))^2 , 2)
[1] TRUE
(2^(0.5))^2 == 2
[1] FALSE

On the off chance you want to reduce size to reduce over-plotting, you

Hello,
from Verzani, simpleR (pdf), p. 80, I created the following function to

# alternative hypothesis: coeff != value

Multivariate normal distributions with PSD variance matrices occur all the time.
The most common example in practice would probably be the distribution of the
vector of residuals from a normal regression. It has a degenerate distribution
wrt R^n because it is subject to p linear restrictions.
