predab.resample can be called by users but usually is not.  It is called by
calibrate.* and validate.* functions in the rms and Design packages (you
neglected to say which package you were using; update to rms if using
Design).  The calibrate and validate functions make it easy to use .632.  

Note that .632 only seems to help when you are using an improper scoring
rule (e.g., proportion classified correctly), not when using smoother
scoring rules such as Brier score, ROC area, etc.
