  arrow_col = "steelblue",
  arrow_scale = 1,
  ...
)

Arguments

object: A fitted PLS model.
comps: Components to display (length two).
circle: Logical; draw the unit circle.
circle_col: Colour of the unit circle.
arrow_col: Colour of the variable arrows.
arrow_scale: Scaling applied to variable vectors.
...: Additional plotting parameters passed to graphics::plot().

Examples

set.seed(123)
X <- matrix(rnorm(60), nrow = 20)
y <- X[, 1] - 0.5 * X[, 2] + rnorm(20, sd = 0.1)
fit <- pls_fit(X, y, ncomp = 2, scores = "r")
plot_pls_variables(fit)
