translate_axes {biplotEZ}

Translate biplot axes

Description

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

Usage

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.

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()

Value

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