\usage{
|
|
CR_FunctionCombiner(events, times = NULL)
|
|
}
|
|
\arguments{
|
|
\item{events}{A vector of integers specifying which competing risks event
|
|
functions should be processed. This should correspond to all of the
|
|
competing risk events that can occur, from 1 to the largest number.}
|
|
|
|
\item{times}{An optional numeric vector that forces the output functions to
|
|
only update at these time points. Pre-specifying the values can result in
|
|
faster performance when predicting, however if the times are not exhaustive
|
|
then the resulting curves will not update at that point (they'll be flat).
|
|
If left blank, the package will default to using all of the time points.}

\description{
|
|
Creates a CompetingRiskFunctionCombiner rJava object, which is used
|
|
internally for constructing a forest. The forest uses it when creating
|
|
predictions to average the cumulative incidence curves, cause-specific
|
|
cumulative hazard functions, and Kaplan-Meier curves generated by each tree
|
|
into individual functions.
|
|
}

|
\details{
|
|
The user only needs to pass this object into \code{\link{train}} as the
|
|
\code{forestResponseCombiner} parameter.
