R help - Aug 2011 - calibration curve for cph()

Hi, the calibrate.cph() function in rms package generate calibration curve for
Cox model on the same dataset where the model was derived using bootstrapping or
cross-validation. If I have the model built on dataset 1, and now I want to
produce a calibration curve for this model on an independent dataset 2, how can
I do that?

Thanks

Build a prediction function using  'Function' that gets applied to set2.
Calibrate and validate.
