Version 1.0 of survival5 will soon be percolating through CRAN.

Survival5 is the R port of the newest version of Terry Therneau's survival
analysis code for S(-PLUS).  It contains a number of bug fixes relative to
survival4, a more robust parametric likelihood maximiser, updated US
mortality ratetables, and facilities for penalised maximum (partial)

The R port REQUIRES version 0.64.1 or later. It also requires the splines
package, and the date package is strongly recommended.

Some further documentation is available in Mayo Clinic technical reports

Please send questions about the R port to me, not to Terry Therneau, since
most of the major changes since survival4 are implemented incompatibly in
R and S.
