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.
expandPred(x, Time = "Time", predTime, time.col = FALSE)data.frame expanded by predTime
Data to be expanded.
Either a character naming the column which contains original time values, or a numeric vector of original times
prediction times to expand data
Logical value indicating whether to attach the new times to the expanded data
