This class encapsulates parameters needed for Hypergeometric testing
of over or under representation of chromosome bands among a selected
gene list using hyperGTest.
Objects from the Class
Objects can be created by calls of the form
new("ChrMapHyperGParams", ...).
Slots
chrGraph:
Object of class "graph". The nodes
are the chromosome bands and the edges describe the tree structure
of the bands. Each node has a "geneIds" node attributes (see
nodeData) which contains a vector of gene IDs annotated at
the given band.
conditional:
Object of class "logical",
indicating whether the test performed should be a conditional
test.
geneIds:
Object of class "ANY": A vector of
gene identifiers. Numeric and character vectors are probably the
only things that make sense. These are the gene ids for the
selected gene set.
universeGeneIds:
Object of class "ANY": A
vector of gene ids in the same format as geneIds defining a
subset of the gene ids on the chip that will be used as the
universe for the hypergeometric calculation. If this is
NULL or has length zero, then all gene ids on the chip will
be used.
annotation:
A string giving the name of the
annotation data package for the chip used to generate the data.
categorySubsetIds:
Object of class "ANY":
If the test method supports it, can be used to specify a subset of
category ids to include in the test instead of all possible
category ids.
categoryName:
A string describing the category.
Usually set automatically by subclasses. For example
"GO".
pvalueCutoff:
The p-value to use as a cutoff for
significance for testing methods that require it. This value will
also be passed on to the result instance and used for display and
counting of significant results. The default is 0.01.
testDirection:
A string indicating whether the test
should be for overrepresentation ("over") or
underrepresentation ("under").
datPkg:
Object of class "DatPkg" used to assist
with dispatch based on type of annotation data available.
Extends
Class "HyperGParams", directly.
