One approach is to build an agent to play the game repeatably and then
calculate the winning odds if a particular card is played.
The logical first step is to implement a playable version of the game using R.

I have a data.frame object like:
> data.frame(x=c('A','A','B','B'), y=c('Ab','Ac','Ba','Bd'))
x y
1 A Ab
2 A Ac
3 B Ba
4 B Bd
how could I create a tree structure object like this:
|---Ab
A---|
_| |---Ac
|
| |---Ba
B---|
|---Bb

Hi,
I'm trying to perform a hierachical, second order CFA.
That's the thing that I need to leave AMOS.
I found some sim.hierarchical and omega stuff, but nothing clear enough.
Can anyone help me?
I just need a simple and clear manual.
Best,
Pablo.

The normal method is to rerun the code. If you use the ggplot2 library you can

That error occurs if you have Inf values in vekkat. Try to see them with
