`km`

calculates the Kaplan-Meier estimates for survival.

To plot the survivor curve, use `plot()`

; for the empirical
intensity curve, use `plot.intensity()`

; for diagnostic curves to
choose a distribution to which the data might belong, use `plot.dist()`

.

`times` |
Vector of times to events or a list of vectors of such times for different individuals. |

`censor` |
Vector of censoring indicators corresponding to the vector of times or to the last time in each vector of a list. |

`group` |
Vector indicating to which group each individual belongs. |

`freq` |
Vector of frequencies for grouped data. |

`cdf` |
If TRUE, calculate the cdf instead of the survivor curve. |

`x` |
An object produced by |

`add` |
Plotting control options. |

`main` |
Plotting control options. |

`type` |
Plotting control options. |

`ylab` |
Plotting control options. |

`xlab` |
Plotting control options. |

`xlim` |
Plotting control options. |

`ylim` |
Plotting control options. |

`lty` |
Plotting control options. |

`...` |
Plotting control options. |

A matrix with class, `km`

, containing the Kaplan-Meier estimates
is returned.
