distance_matrix function

Data Frame to Distance Matrix

distance_matrix(df = NULL, name_column = NULL, distance = "euclidean")

Arguments

• df: (required, data frame) Data frame with numeric columns to transform into a distance matrix. Default: NULL
• name_column: (optional, column name) Column naming individual time series. Numeric names are converted to character with the prefix "X". 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

square matrix

Examples

#compute distance matrix
m <- distance_matrix(
  df = cities_coordinates,
  name_column = "name",
  distance = "euclidean"
)

#get data used to compute the matrix
attributes(m)$df

#check matrix
