interp_cif: Interpolate CIF matrix

In survdistr: Survival Distribution Container with Flexible Interpolation Methods

Interpolate CIF matrix

Description

Interpolates cumulative incidence (CIF) functions (corresponding to one competing event only) using left-continuous constant interpolation.

Usage

interp_cif(x, times = NULL, eval_times = NULL, add_times = TRUE, check = TRUE)

Arguments

x	(matrix()) CIF matrix (rows = observations, columns = time points).
times	(numeric() | NULL) Anchor time points. If NULL, extracted from colnames(x).
eval_times	(numeric() | NULL) New time points at which to interpolate. Values need to be unique, increasing non-negative numbers. If NULL, the anchor times are used.
add_times	(logical(1)) If TRUE, attach eval_times as colnames in the output matrix.
check	(logical(1)) If TRUE, run input matrix validation checks using assert_prob(); set to FALSE to skip checks (NOT recommended for external use).

Value

Interpolated CIF matrix.
