## S3 method for class 'Surv'

x	A Surv object
l	length of arrow. Length is l / nrow(x)
...	Additional arguments. These are passed to as ... (an ellipsis) to the following functions, respectively: graphics::arrows for plotting right- or left-censored observations graphics::segments for plotting interval-censored observations

Value

A graph (base graphics). The type of graph depends on the type of the Surv object. This is given by attr(s, which="type") :

counting	Lines with an arrow pointing right if right censored.
right	Lines with an arrow pointing right if right censored.
