S-PLUS contains extensive survival analysis facilities written by Terry Therneau (Mayo Foundation). The functions in S-PLUS 3.3 and 3.4 are modified versions of code available from statlib as survival4 (see Appendix C for further information); S-PLUS 3.2 and earlier versions used the rather different survival2 . As the code for survival4 is available1, we strongly recommend its use.
