Sample from an mjoint object
Generic function used to sample a subset of data from an object
of class mjoint with a specific number of subjects.
sampleData(object, size = NULL, replace = TRUE)
object |
an object inheriting from class |
size |
number of subjects to include in the sampled subset. If
|
replace |
use replacement when sampling subjects? Default is
|
This function is primarily intended for internal use in the
bootSE function in order to permit bootstrapping. However, it
can be used for other purposes given a fitted mjoint object.
A list of 2 data.frames: one recording the requisite longitudinal outcomes data, and the other recording the time-to-event data.
