Version 2.37-5 of survival has just been submitted to CRAN. In this new release
the tt()
function was made externally invisible, so you should not have problems.  This
will take a
few days to propogate out to the various mirrors (perhaps longer if the Windows
build has
issues).

This question of how to best deal with functions that only have meaing within a
coxph
model statement came up on R-devel just over a year ago, and I'm just now
implementing the
workaround found there.  In time the cluster(), pspline(), ridge() and frailty()
functions
are likely to receive the same treatment.
