Custom fill, colour and text colours for ggplot2

Description

This function lets the user use pre-defined default colours. Check your lares_pal()$labels scale. Feel free to use gg_vals() to debug colours used in latest plot.

Usage

gg_fill_customs(column = "fill", ...)

gg_colour_customs(column = "colour", ...)

gg_text_customs(column = "colour", ...)

gg_vals(layer = "fill", column = layer, cols = NULL, ...)

Arguments

column	Character. Select any of "fill" or "colour" to use on your lares_pal()$labels palette.
...	Allow additional parameters not used.
layer	Character. Select any of "fill", "colour", or "label" to get the layer containing the colours labels you wish to colour.
cols	Data.frame. Customize colour palette with a data.frame. Must contain values, fill, and colour columns.

Details

Notice that when the layer defined is any of GeomPoint, GeomLine, GeomText or GeomLabel, gg_colour_customs() will force column = "fill" parameter.

Value

Same as scale_fill_manual or scale_colour_manual but with custom palette applied.

Examples

library("ggplot2")
# Generic plot function to run examples to
run_plot <- function(add_fxs = TRUE) {
  p <- data.frame(station = c("spring", "summer", "fall", "winter"), num = 1:4) %>%
    ggplot(aes(x = station, y = num, fill = station)) +
    geom_col() +
    geom_text(aes(y = 0.5, label = num, colour = station), size = 6)
  if (add_fxs) p <- p + gg_fill_customs() + gg_colour_customs()
  return(p)
}
# Default colours
run_plot()
# Check last colours used
gg_vals("fill", "fill")
gg_vals("colour", "colour")
# Change any default colour
options("lares.colours.custom" = data.frame(
  values = c("summer", "winter"),
  fill = c("pink", "black"),
  colour = c("black", "white")
))
run_plot()
# Check last colours used
gg_vals("fill", "fill")
gg_vals("colour", "colour")
# Reset to default colours
options("lares.colours.custom" = NULL)
# Notice you can use 'pal = 4' argument on theme_lares() too
run_plot(add_fxs = FALSE) + theme_lares(pal = 4)
