plot_mfd function

Plot a Multivariate Functional Data Object.

Plot an object of class mfd using ggplot2

and patchwork.

plot_mfd(
  mfdobj,
  mapping = NULL,
  data = NULL,
  stat = "identity",
  position = "identity",
  na.rm = TRUE,
  orientation = NA,
  show.legend = NA,
  inherit.aes = TRUE,
  type_mfd = "mfd",
  y_lim_equal = FALSE,
  ...
)

Arguments

• mfdobj: A multivariate functional data object of class mfd.
• mapping: Set of aesthetic mappings additional to x and y as passed to the function ggplot2::geom:line.
• data: A data.frame providing columns to create additional aesthetic mappings. It must contain a factor column "id" with the replication values as in mfdobj$fdnames[[2]]. If it contains a column "var", this must contain the functional variables as in mfdobj$fdnames[[3]].
• stat: See ggplot2::geom_line.
• position: See ggplot2::geom_line.
• na.rm: See ggplot2::geom_line.
• orientation: See ggplot2::geom_line.
• show.legend: See ggplot2::geom_line.
• inherit.aes: See ggplot2::geom_line.
• type_mfd: A character value equal to "mfd" or "raw". If "mfd", the smoothed functional data are plotted, if "raw", the original discrete data are plotted.
• y_lim_equal: A logical value. If TRUE, the limits of the y-axis are the same for all functional variables. If FALSE, limits are different for each variable. Default value is FALSE.
• ...: See ggplot2::geom_line.

Returns

A plot of the multivariate functional data object.

Examples

library(funcharts)
library(ggplot2)
mfdobj <- data_sim_mfd()
ids <- mfdobj$fdnames[[2]]
df <- data.frame(id = ids, first_two_obs = ids %in% c("rep1", "rep2"))
plot_mfd(mapping = aes(colour = first_two_obs),
         data = df,
         mfdobj = mfdobj)
