[BioC] cox PH model - KM curve

[Adrian Johnson]

Dear group:
I have gene expression data matrix (after RMA) as a matrix. In another
table (as data frame) I have survival data. I have 25 genes for which
I want to plot a Kaplan-meier curves based on cox model for these 25
genes. Is there a workflow to do this analysis.
I tried phenoTest, however I do not know how to make use of
heatmapPhenoTest function on a given gene.

I appreciate your help. Thanks
Adrian.
