1. under unix prompt %, type "add st370_info"

2. type "ESS R" under unix prompt %; you will see an emacs window; you may want to hit several "return" key until you get an R prompt >.

3. Include library "survival", "Design" and "KMsurv" by typing "library(survival)", "library( Design)", "library( KMsurv)", each of which is under R prompt ">";  then you can use most of the R functions for survival analysis.
