get.uppdwn

Determine UP and DOWN for the NRI calculation

Internaly used function to detemine subjects who belong to UP and DOWN.

get.uppdwn(time, event, objs, flag.mdl, flag.prd, flag.rsk, t0, updown,
           cut, get.risk, msg = FALSE)

`time`	Vector of follow up times.
`event`	Vector of event indicators, 1 for event of interest, 0 for censoring.
`objs`	List of data.
`flag.mdl, flag.prd, flag.rsk`	Logical values to determine the type of calculation based on the input data.
`t0`	Scalar value indicating a time to determine evnet/non-event.
`updown`	Character to specify the method to determine `UP` and `DOWN`.
`cut`	Scalar or vector to specify the cutoff value(s) of predicted risks for determining `UP` and `DOWN`. See also `cut` in `nricens` or `nribin`.
`get.risk`	R function to calculate individual risks.
`msg`	Logical value to display computation process. Setting `FALSE` leads silent execution.
