Description Usage Arguments Value Author(s) References Examples
This function computes signature scores and risk classifications from gene expression values following the algorithm used for the rorS signature as published by Parker et al 2009.
1 |
data |
Matrix of gene expressions with samples in rows and probes in columns, dimnames being properly defined. |
annot |
Matrix of annotations with at least one column named "EntrezGene.ID", dimnames being properly defined. |
do.mapping |
|
mapping |
Matrix with columns "EntrezGene.ID" and "probe" used to force the mapping such that the probes are not selected based on their variance. |
verbose |
|
score |
Continuous signature scores |
risk |
Binary risk classification, |
mapping |
Mapping used if necessary. |
probe |
If mapping is performed, this matrix contains the correspondence between the gene list (aka signature) and gene expression data. |
