Move plot 2

Create animated biplot on samples and variables in a biplot

Usage

moveplot2(
  bp,
  time.var,
  group.var,
  move = TRUE,
  hulls = TRUE,
  scale.var = 5,
  align.time = NA,
  reflect = NA
)

Arguments

bp

biplot object from biplotEZ

time.var

time variable

group.var

group variable

move

whether to animate (TRUE) or facet (FALSE) samples and variables, according to time.var

hulls

whether to display sample points or convex hulls

scale.var

scaling the vectors representing the variables

align.time

a vector specifying the levels of time.var for which the biplots should be aligned. Only biplots corresponding to these time points will be used to compute the alignment transformation.

reflect

a character vector specifying the axis of reflection to apply at each corresponding time point in align.time. One of FALSE (default), "x" for reflection about the x-axis, "y" for reflection about the y-axis and "xy" for reflection about both axes.

Value

An animated or a facet of biplots based on the dynamic frame.

Examples

data(Africa_climate)
bp <- biplotEZ::biplot(Africa_climate, scaled = TRUE) |> biplotEZ::PCA()
# \donttest{
if(interactive()) {
bp |> moveplot2(time.var = "Year", group.var = "Region", hulls = TRUE, move = TRUE)}# }
