get_mfd_array function

Get Multivariate Functional Data from a three-dimensional array

get_mfd_array(
  data_array,
  grid = NULL,
  n_basis = 30,
  n_order = 4,
  basisobj = NULL,
  Lfdobj = 2,
  lambda = NULL,
  lambda_grid = 10^seq(-10, 1, length.out = 10),
  ncores = 1
)

Arguments

• data_array: A three-dimensional array. The first dimension corresponds to argument values, the second to replications, and the third to variables within replications.
• grid: See get_mfd_list.
• n_basis: See get_mfd_list.
• n_order: #' See get_mfd_list.
• basisobj: #' See get_mfd_list.
• Lfdobj: #' See get_mfd_list.
• lambda: See get_mfd_list.
• lambda_grid: See get_mfd_list.
• ncores: Deprecated. See get_mfd_list.

Returns

An object of class mfd. See also ?mfd for additional details on the multivariate functional data class.

Examples

library(funcharts)
library(fda)
data("CanadianWeather")
mfdobj <- get_mfd_array(CanadianWeather$dailyAv[, 1:10, ],
                        lambda = 1e-5)
plot_mfd(mfdobj)
