[R] survival: fitting equation to survival curve?

[Lancaster, Robert (Orbitz)]

I was able to resolve my issue.  I assumed my survival rates followed an exponential, so took the log of them and fit the resulting values to a linear model.

Would survreg allow me skip this step?  I'm a newbie to the survival package so am not very familiar with its capabilities.

Given a survfit object, is it possible to fit an equation to the resulting survival curve?  Is this possible?  What about with a coxph or survreg object?

TIA,
Rob
