tsl_join: Join Time Series Lists

In BlasBenito/distantia: Advanced Toolset for Efficient Time Series Dissimilarity Analysis

Join Time Series Lists

Description

Joins an arbitrary of time series lists by name and time. Pairs of zoo objects are joined with zoo::merge.zoo(). Names that are not shared across all input TSLs are ignored, and observations with no matching time are filled with NA and then managed via tsl_handle_NA() depending on the value of the argument na_action.

Usage

tsl_join(..., na_action = "impute")

Arguments

...	(required, time series lists) names of the time series lists to merge.
na_action	(required, character) NA handling action. Available options are: "impute" (default): NA cases are interpolated from neighbors as a function of time (see zoo::na.approx() and zoo::na.spline()). "omit": rows with NA cases are removed.

Value

time series list

Examples

#generate two time series list to join
tsl_a <- tsl_simulate(
  n = 2,
  cols = 2,
  irregular = TRUE,
  seed = 1
)

#needs renaming
tsl_b <- tsl_simulate(
  n = 3,
  cols = 2,
  irregular = TRUE,
  seed = 2
) |>
  tsl_colnames_set(
    names = c("c", "d")
  )

#join
tsl <- tsl_join(
  tsl_a,
  tsl_b
)

#plot result
if(interactive()){
  tsl_plot(
    tsl = tsl
  )
}
