an optional matrix or data frame (or similar: see

subset 
an optional vector specifying a subset of observations to be used. 
na.action 
a function which indicates what should happen when

For allpairs comparisons in an onefactorial layout with nonnormally distributed residuals AndersonDarling's allpairs comparison test can be used. A total of m = k(k1)/2 hypotheses can be tested. The null hypothesis H_{ij}: F_i(x) = F_j(x) is tested in the twotailed test against the alternative A_{ij}: F_i(x) \ne F_j(x), ~~ i \ne j.
This function is a wrapper function that sequentially
calls adKSampleTest
for each pair.
The calculated pvalues for Pr(>T2N)
can be adjusted to account for Type I error multiplicity
using any method as implemented in p.adjust
.
A list with class "PMCMR"
containing the following components:
a character string indicating what type of test was performed.
a character string giving the name(s) of the data.
lowertriangle matrix of the estimated quantiles of the pairwise test statistics.
lowertriangle matrix of the pvalues for the pairwise tests.
a character string describing the alternative hypothesis.
a character string describing the method for pvalue adjustment.
a data frame of the input data.
a string that denotes the test distribution.
