Usage

# S3 method for rfsrc
plot.competing.risk(x, plots.one.page = FALSE, ...)

Arguments

x

An object of class (rfsrc, grow) or (rfsrc, predict).

plots.one.page

Should plots be placed on one page?

...

Further arguments passed to or from other methods.

Details

Given a random survival forest object from a competing risk analysis (Ishwaran et al. 2014), plots from top to bottom, left to right: (1) cause-specific cumulative hazard function (CSCHF) for each event, (2) cumulative incidence function (CIF) for each event, and (3) continuous probability curves (CPC) for each event (Pepe and Mori, 1993).

Does not apply to right-censored data. Whenever possible, out-of-bag (OOB) values are displayed.
