Greetings,

I am new to R and have been comparing CPH survival analysis hazard ratios 
between R and SAS PhReg.  The binary covariates' HRs are the same, however 
the continuous variables, for example age, have quite different HRs 
although in the same direction.  SAS PhReg produces HRs which are the 
change in risk for every one increment change in the independent variable. 
 How do I interpret the HRs produced by R?    Thanks much, C
