Does anyone tell me how to retrieve the data frame column names?
I'm working on coxph model to analyze survival data of Affy DNA chips.
I get the coxph coef p-value for each probe and want output the probe name
with the p-value. The probe names are the data frame column names.
How can I do this?
Thanks for your help.
