R中的CARET包中的createTimeSlices函数

Question

I am working with multivariate financial time series data and having problems using the createTimeSlices function. I cannot find any use of the function except the one used by Max Kuhn . Can anybody help me in understanding the usage of the function?

The documentation is being "improved" on this feature (in other words, it currently sucks). Another person contacted me recently about this and here is the example:

library(caret)
library(ggplot2)
data(economics)
myTimeControl <- trainControl(method = "timeslice",
                              initialWindow = 36,
                              horizon = 12,
                              fixedWindow = TRUE)

plsFitTime <- train(unemploy ~ pce + pop + psavert,
                    data = economics,
                    method = "pls",
                    preProc = c("center", "scale"),
                    trControl = myTimeControl)
