R help - Aug 2006 - [Fwd: Trend test and test for homogeneity of odd-ratios]

I partly answered my question since independence_test() function in coin package
apparently do
Cochran-Armitage trend test just like Eric Lecoutre's function tabletrend()
- slightly modified here:

 > independence_test(pheno ~ geno, data = dat2, teststat = "quad",
scores = list(geno = c(0, 1, 2)))

         Asymptotic General Independence Test

data:  pheno by groups 1 < 2 < 3
chi-squared = 0.2268, df = 1, p-value = 0.6339

 > tabletrend(with(dat2, table(pheno, geno)))
[1] 0.6338308

Dear r-users,

I am looking for some R functions to do Cochran-Armitage trend test for 2*3
tables (binary phenotype
vs. genotypes) and for testing the homogeneity of odds ratios within 2*3*k
tables (binary phenotype
vs. genotypes vs. strata).

In R-Help archives, I've found a 2003 script by Eric Lecoutre for
Cochran-Armitage trend test and a
script for Breslow-Day test for 2*2*k tables.

Could someone please tell we if there were some functions available on CRAN to
do such tests ?

Thanks,

jacques
