prism_shape_pal: Prism shape palettes

Description

Shape palettes that approximate those used in GraphPad Prism. No unicode characters are used, only the default symbols available in R.

Usage

prism_shape_pal(palette = c("default", "filled", "complete"))

Value

Returns a function which takes a single integer as its only argument and returns a character vector of integers which correspond to R plot pch symbols. See the examples below for usage.

Arguments

palette

string. Palette name, one of: default, filled, or complete.

Details

The default palette supports up to 9 values. It does not use any symbols with a fill.

The filled palette supports up to 10 values. The first 5 symbols have a fill.

The complete palette supports up to 14 values. Symbols 5 to 9 have a fill.

Examples

library(ggplot2)

## list all available shape palettes
ggprism_data$shape_palettes

## select some shapes from a palette
prism_shape_pal(palette = "filled")(4)

## see all the shapes in a specific palette
# define a function for convenience
show_shapes <- function(palette) {
  df_shapes <- ggprism_data$shape_palettes[[palette]][, -1]
  df_shapes$pch_f <- factor(df_shapes$pch, levels = df_shapes$pch)

  ggplot(df_shapes, aes(x = 0, y = 0, shape = pch)) +
    geom_point(aes(shape = pch), size = 5, fill = 'red') +
    scale_shape_identity() +
    facet_wrap(~ pch_f) +
    theme_void()
}

# show the shapes in the palette "complete"
show_shapes("complete")
