goCluster FDR analysis {goCluster} | R Documentation |
These three functions are used to perform FDR analysis within
goCluster
. They will be combined to a single function for the
next version.
randomizeTree(X, elements) mergeAnno(X, i) selectAnnoStats(X, threshold)
X |
A lists of lists. |
elements |
The total number of selectable elements. |
i |
Index of the annotation to select. |
threshold |
Holds p-value thresholds for each annotation. |
randomizeTree
will accept a tree as its input
and it will fill each terminal node of the tree with randomized
integers. The number of integers is determined by the size of the
respective terminal node. The minial integer possible is one, the
maximal integer is given by the option elements
.
mergeAnno
will also accept a tree as input and will return the
element i
among the list one level above the terminal nodes of
a leaf.
selectAnnoStats
will select all elements from the tree X
that have a p-value below the threshold given in the threshold
option. The length of the threshold
element has to match the
number of annotations analyzed and represented by the tree X
.
