This method compares the values of all

Depending on the composition of each annotation,
will perform either a chi-squared test or an ANOVA test.

A character string. The annotation column against which to compare all other annotation terms (i.e., to test as the independent variable).
A numeric scalar. The p-value cutoff that determines when

This method performs two kinds of comparisons. First, it tests all
annotation variables against the annotation supplied by the
argument for each provided
ExprsArray object. In other words,
colBy argument determines which annotation to use as the
independent variable for "internal" comparisons. Second, it tests
all annotation variables between the provided
array.valid = NULL will skip the between comparisons.
This method will test annotations using either a chi-squared test or an
ANOVA test depending on the class of the values stored by the tested column.
The presence of a "character" or "factor" in the tested column will trigger
a chi-squared test. As such, this method requires the user to select
colBy annotation that contains categorical data (i.e., to use as
the independent variable).
We anticipate that this method will serve as a useful adjunct to
modCluster. However, it may also help in quickly determining
whether the data
split has yielded comparable training and

A list of three logical vectors. The first and second elements
of the list correspond to "internal" comparisons for the two provided
ExprsArray objects, respectively. The third element of the list
corresponds to comparisons made between the provided objects.
