#' Compute predictions using an oblique random survival forest.
#' @importFrom pec predictSurvProb
#' @param object A fitted model from which to extract predicted survival probabilities
#' @param newdata A data frame containing predictor variable combinations for which to compute predicted survival probabilities.
#' @param times A vector of times in the range of the response variable, e.g. times when the response is a survival object, at which to return the survival probabilities.
#' @param ... Additional arguments that are passed on to the current method.
#' @return A matrix of survival probabilities containing 1 row for each observation and 1 column for each value in times.
