Summary of a Survival Curve

Description:

     Returns a list containing the survival curve, confidence limits
     for the curve, and other information.

Usage:

     ## S3 method for class 'survfit':
     summary(object, times, censored=FALSE, scale=1, ...)

Arguments:

  object: output from a call to 'survfit'. 

   times: vector of times; the returned matrix will contain 1 row for
          each time. This must be in increasing order and missing
          values are not allowed. If 'censored=T', the default 'times'
          vector contains all the unique times in 'fit', otherwise the
          default 'times' vector uses only the event (death) times. 

censored: logical flag: should the censoring times be included in the
          output? This is ignored if the 'times' argument is present. 

   scale: rescale the survival time, e.g., if the input data to
          'survfit' were in days, 'scale=365.25' would scale the output
          to years. 

     ...: other unused arguments

Value:

     a list with the following components
