chrBandInciMat {Category} | R Documentation |
These functions return a 0/1 incidence matrix with a row for each gene ID with at least one chromosme band annotation and a column for each chromosome band with at least one gene annotation.
chrBandInciMat(chip, univ = NULL) makeChrBandInciMat(chrGraph)
chip |
A string giving the annotation source. For example, "hgu133plus2" |
univ |
A vector of gene IDs (these should be Entrez IDs for
most annotation sources). The the annotations will be limited
to those in the set specified by univ .
If univ is NULL (default), then the gene IDs are those
found in the annotation data source. |
chrGraph |
A graph object as returned by makeChrBandGraph |
A (0/1) incidence matrix with gene IDs as rows and chromosome bands
as columns. A 1
in m[i, j]
indicates that the geneID
rownames(m)[i]
is annotated at chromosome band
colnames(m)[j]
.
