- summary.survfit(fit, times, censored=F, scale=1)
-
- _A_r_g_u_m_e_n_t_s:
-
- fit:
- output from a call to survfit.
-
- times:
- vector of the 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 time vector contains all the unique times in
- fit.list, otherwise the default time 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" would scale the prin-
- tout to years.
-
- Value:
-
- a list with the following components
-
- _A_r_g_u_m_e_n_t_s:
-
- time:
- the timepoint on the curve.
-
- surv:
- the value of the survival curve at time t+0.
-
- n.risk:
- the number of subjects at risk at time t-0 (but see the
- comments on weights in the survfit help file).
-
- n.event:
- if the times argument is missing, then this column is
- the number of events that occurred at time t. Other-
- wise, it is the cumulative number of events that have
- occurred since the last time listed until time t+0.
-
- std.dev:
- the standard deviation of the survival value.
-
- lower CI:
- lower confidence limits for the curve.
-
- upper CI:
- upper confidence limits for the curve.
-
- strata:
- the number of points per curve. If there are multiple
- curves in this result, then the time, surv, etc vectors
- will contain multiple curves, pasted end to end, and
- length(surv)=sum(strata). The names of the strata vec-
- tor are the labels for the curves.
-
- call:
- the statement used to create the fit object.
-
- na.action:
- passed through from fit, if present.
-
- survfit, 'print.summary.survfit'.
-
- _E_x_a_m_p_l_e_s:
-
- summary( survfit( futime, fustat))
