Dear R-Help:
From multiple sources comparing methods of tree classification and
tree regressions on various data sets
are implemented in R.
I see that CHAID, but not Exhaustive CHAID, is in the R-forge, and I write to
ask if there are plans to create a package which employs the Exhaustive CHAID
strategy. Right now the best source I can find is in SPSS-IBM and I feel a
bit disloyal to R using it.

not understood the recommendation or
the proper likelihood ratio test in question (or both) for I get this error
message: Error: $ operator not defined for this S4 class.
Would someone be kind enough to point out my blunder?
Thank you,

test,
the variable ozone is not numeric. Can someone please help? This behavior is
occurring with multiple data sets loaded from outside R. Thank you in advance.
Michael Grant
Example:
test
ozone garden
1 3 A
2 5 B
3 4 A
4 5 B
5 4 A
6
' going at the same
time, with each being unrecognized by the other within R.
Many thanks,

PLEASE do read
I wish to test the hypothesis of mu equal to or less than 5 against the
specific alternative mu equal to or greater than 7. I am unable to find how to
persuade R to do this with any function (e.g. t.test). Suggestions?

Maybe 'tk_choose.dir' in the tcltk package will do what you want.

Dario,
Checkout the 'plot.axes' argument to 'filled.contour'.

I believe the binom.test procedure is producing one tailed p values
rather than the two tailed value implied by the alternative hypothesis
language. A textbook and SAS both show 2*9.94e-07 = 1.988e-06 as the
two tailed value. As does the R summation syntax from R below. It
looks to me like the
should relatively
straight-forward.

Dear Danilo:
Here is one approach with the formal reference being:
Computational Statistics Data Analysis 23 ( 1997 ) 355-372

STATISTICS
DATA ANALYSIS
Generalization of the geometric mean
functional relationship

Sorry no previous message text or addresses, but I just cleaned my mailbox
and then found something relevant. Regarding the Piper diagram. I just
noticed the 'hydrogeo' package on CRAN, courtesy of one Myles English. That
should be what you need or close to it.
Best regards,
Michael Grant
