scale_shape_girafe_filled: Filled shapes for ggiraph interactive plots

In david-barnett/microViz: Microbiome Data Analysis and Visualization

Filled shapes for ggiraph interactive plots

Description

Generates a custom ggplot2 shape scale, as used in ord_explore's ordination. Uses filled shapes, therefore fill aesthetic must be set, in addition to colour, to have filled shapes. Points with NA values for the shape variable are shown as hollow circles.

Usage

scale_shape_girafe_filled()

Details

Composite shapes e.g. number 7 "square cross" cause ggiraph interactive plots to fail when a variable shape and tooltip is set.

Shapes used are, in order: "circle filled", "triangle filled", "square filled", "diamond filled", and "triangle down filled"

Value

ggplot2 Scale object

Examples

microViz::ibd %>%
  tax_fix() %>%
  phyloseq_validate() %>%
  tax_transform(rank = "Genus", trans = "clr") %>%
  ord_calc(
    method = "PCA"
  ) %>%
  ord_plot(
    axes = c(1, 2),
    plot_taxa = 1:6,
    colour = "DiseaseState", fill = "DiseaseState",
    shape = "circle", alpha = 0.5,
    size = 3
  ) +
  scale_shape_girafe_filled()
