dmvnorm
...stack overflow check that always trips
because the thread's stack is different from what R is expecting.
+ Therefore, I need a C version of dmvnorm.
+ The mvtnorm package maintainer is not interested in
R_RegisterCCallable.
Can a C version of dmvnorm get added to the R core?

...eward", "feedback", "goal"), class = "data.frame")

When I try this, column ddd has 1 fewer digits than expected. See the
attached screenshot.
Why don't all the columns have the same number of digits displayed?

I think this is a good idea. Is there a reason why it got no interest?
Slippery slope?
Or maybe others were also just occupied trying to figure out how
Joshua's second message had timestamp earlier than his first message?

[kjbeath@kagi.com: Remedial stats]
It seems like the Bayesian folks like to hide. Hey, I just want to get the
job done whether using frequency or Bayesian stats. Can anybody suggest
a good introduction to Bayesian Analysis?
