Objects of this class are returned by the functions:
binom.test,
chisq.test,
cor.test
,
fisher.test,
friedman.test,
kruskal.test,
mantelhaen.test,
mcnemar.test
,
prop.test,

wilcox.test.
All of these functions, in the statistical inference module, create objects
of class
"htest".

the estimation of a test statistic
given null and alternative hypotheses, and a confidence level.
The methods used in estimating these test statistics are varied ranging from
classical to robust and nonparametric approaches.
The class
"htest" has methods for the following generic function:
print
The
"htest" objects are implemented as lists
with the following components:
names attribute indicating
