Translate biplot axes — translate

Automatically or manually translate the axes away from the center of the plot

translate_axes(bp, delta = 0, swop = FALSE, distances = NULL)

Arguments

bp: An object of class biplot
delta: numeric value indicating distance between axes
swop: logical. Change the direction in which axes are translated
distances: numeric vector of distances. Used to manually parallel translate the axes.

Value

An object of class biplot with the translated distances appended under bp$axes

Details

This function uses the same algorithm implemented in TDAbiplot in the bipl5 package. It translates the axes out of the center of the plot. Correlated axes generally gets translated in the same direction.

This function calculates the orthogx and orthogy paramaters in axes()

Examples


#Translate the axes out of the plot center

bp <- biplot(state.x77,scaled = TRUE)|> 
      CVA(state.region) |> 
      translate_axes(swop=TRUE,delta =0.2)|>
      plot(exp.factor=3)


#adjust the distance of an axis

dist <- bp$axes$translate_distance
dist[7] <- 0.4
bp |> translate_axes(delta = 0.2, distances=dist) |> plot()
