In NMML/crawl: Fit Continuous-Time Correlated Random Walk Models to Animal Movement Data

Expand a time indexed data set with additional prediction times

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(x, Time = "Time", predTime, time.col = FALSE)

Arguments

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

Value

data.frame expanded by predTime

Examples

#library(crawl)
origTime <- c(1:10)
x <- cbind(rnorm(10), c(21:30))
predTime <- seq(1,10, by=0.25)
expandPred(x, Time=origTime, predTime, time.col=TRUE)
