distantia_ls function

Lock-Step Dissimilarity Analysis of Time Series Lists

Minimalistic but slightly faster version of distantia() to compute lock-step dissimilarity scores.

distantia_ls(tsl = NULL, distance = "euclidean")

Arguments

• tsl: (required, time series list) list of zoo time series. Default: NULL
• distance: (optional, character vector) name or abbreviation of the distance method. Valid values are in the columns "names" and "abbreviation" of the dataset distances . Default: "euclidean".

Returns

data frame:

• x: time series name.
• y: time series name.
• distance: name of the distance metric.
• psi: psi dissimilarity of the sequences x and y.

Examples

#load fagus_dynamics as tsl
#global centering and scaling
tsl <- tsl_initialize(
  x = fagus_dynamics,
  name_column = "name",
  time_column = "time"
) |>
  tsl_transform(
    f = f_scale_global
  )

if(interactive()){
  tsl_plot(
    tsl = tsl,
    guide_columns = 3
    )
}

#lock-step dissimilarity analysis
df_ls <- distantia_ls(
  tsl = tsl,
  distance = "euclidean"
)
