Move a ggplot Layer

Use this function to move a certain plot layer up or down.

Usage

move_layer(plot, move = -1, layer = length(plot$layers))

Arguments

plot

A ggplot object.

move

Number of layers to move layer: a negative value moves it down (drawn earlier, so below other layers), a positive value moves it up. The new position is limited to the existing layers. Defaults to -1, one layer down.

layer

The number of the layer to move, defaults to the top layer.

Value

A ggplot object with the layers in the new order.

Examples

p <- plot2(iris, Sepal.Length, Sepal.Width, colour = "grey75") |>
  add_line(y = mean(Sepal.Width), colour = "red", linewidth = 2)
#> Using type = "point" since both axes are numeric

# the line is drawn on top of the points
p


# move the line one layer down, below the points
move_layer(p)
