survfit.object

This class of objects is returned by the <code>survfit</code> class of functions
to represent a fitted survival curve.<p></p><p>
Objects of this class have methods for the functions <code>print</code>,
<code>summary</code>, <code>plot</code>, <code>points</code> and <code>lines</code>.</p>

survival

survival analysis: descriptive statistics, two-sample
  tests, parametric accelerated failure models, Cox model. Delayed entry
  (truncation) allowed for all models; interval censoring for parametric
  models.

Thomas Lumley

Survival analysis, including penalised likelihood.

survfit.object function

Survfit objects that contain multiple survival curves can be subscripted.
This is most often used to plot a subset of the curves.
Usually a single subscript will be used.  In one particular case --
survival curves for multiple covariate values, from a Cox model that includes
a <code>strata</code> statement -- there is a matrix of curves and 2 subscripts may
be used.
(In this case <code>summary.survfit</code> will also print the data as a matrix).
