Color scales for bricks - ggplot2 extension

Source: R/scale-brick.R

brickr counterpart to ggplot2::scale_fill_discrete() to map bar colors to the palette of LEGO mold colors.

scale_fill_brick(brick_theme = "classic", ...)

Arguments

brick_theme

Color palette for bricks. Same as brickr::theme_brick(). Options include: c("classic", "hp", "sw_light", "sw_dark", "friends", "elves", "ninja", "classy", "city", "ocean", "movie", "space", "jurassic", "duplo", "superhero", "80s", "rainbow7", "rainbow13", "doublerainbow", "blue").
...

Arguments passed on to discrete_scale

palette

A palette function that when called with a single integer argument (the number of levels in the scale) returns the values that they should take.

breaks

One of:

  • NULL for no breaks

  • waiver() for the default breaks computed by the transformation object

  • A character vector of breaks

  • A function that takes the limits as input and returns breaks as output

limits

A character vector that defines possible values of the scale and their order.

drop

Should unused factor levels be omitted from the scale? The default, TRUE, uses the levels that appear in the data; FALSE uses all the levels in the factor.

na.translate

Unlike continuous scales, discrete scales can easily show missing values, and do so by default. If you want to remove missing values from a discrete scale, specify na.translate = FALSE.

na.value

If na.translate = TRUE, what value aesthetic value should missing be displayed as? Does not apply to position scales where NA is always placed at the far right.

scale_name

The name of the scale

name

The name of the scale. Used as the axis or legend title. If waiver(), the default, the name of the scale is taken from the first mapping used for that aesthetic. If NULL, the legend title will be omitted.

labels

One of:

  • NULL for no labels

  • waiver() for the default labels computed by the transformation object

  • A character vector giving labels (must be same length as breaks)

  • A function that takes the breaks as input and returns labels as output

guide

A function used to create a guide or its name. See guides() for more info.

super

The super class to use for the constructed scale

Examples

df <- data.frame(trt = c("a", "b", "c"), outcome = c(2.3, 1.9, 3.2))
p <- ggplot(df, aes(trt, outcome)) +
  geom_brick_col(aes(fill = trt)) +
  coord_brick()

p  + scale_fill_brick()

#Select a brick_theme and use with theme_brick()
tm <- "hp"
p  +
 scale_fill_brick(tm) +
 theme_brick(tm)
