Description

Expands a covariate data frame (or vector) that has a separate time index by inserting prediction times and duplicating the covariate values for all prediction time between subsequent data times.

Usage

expandPred(origTime, x, predTime)

Arguments

origTime

Original time index for the data to be expanded.

x

Data to be expanded.

predTime

prediction times to expand data.

Value

• data.frame expanded by predTime.

Examples

origTime <- c(1:10)
x <- cbind(rnorm(10), c(21:30))
predTime <- seq(1,10, by=0.25)
expandPred(origTime, x, predTime)
