View source: R/facopy_internal_v45.r
Performs gene-set enrichment analysis of cancer copy number data, based on a gene table, a facopyInfo
object and the correlations between gene copy number and expression data.

|
fad |
|
geneTable |
A table with the format of |
cor |
A list generated by a call to |
outFolder |
The folder to which to write the enrichment results. |
pvalThr |
Maximum p-value required to consider a gene to be significantly associated. |
corThr |
Minimum R2 required to consider a gene's copy number and expression to be sufficiently correlated. |
plotThr |
Pathways from Biocarta, KEGG and Reactome with lower p-values than this integer will have their graphs plotted in the output folder. |
Only use this function and calculateCor
if you selected some kind of gene collection as genomic features.
The input gene table is returned with correlation values attached, ordered by p-value and then by R2.
