survival5 is released

[Thomas Lumley]

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)
likelihood.

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
from:
 http://www.mayo.edu/hsr/main/people/therneau.html

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.
