plotCostMatrix: Plotting paths

Description

Method for plotting low cost paths in the TWDTW cost matrix.

Usage

plotCostMatrix(
  x,
  timeseries.labels = NULL,
  patterns.labels = NULL,
  matrix.name = "costMatrix"
)

Value

A ggplot object.

Arguments

x

An object of class twdtwMatches.

timeseries.labels

The label or index of the time series. Default is 1.

patterns.labels

A vector with labels of the patterns. If not declared the function will plot one alignment for each pattern.

matrix.name

A character. The name of the matrix to plot, "costMatrix" for accumulated cost, "localMatrix" for local cost, or "timeWeight" for time-weight. Default is "costMatrix".
