Sp + scale_color_brewer(palette = "Dark2") scale_color_brewer() for lines and pointsīp + scale_fill_brewer(palette = "Dark2").scale_fill_brewer() for box plot, bar plot, violin plot, dot plot, etc.Two color scale functions are available in ggplot2 for using the colorbrewer palettes: You can also view a single RColorBrewer palette by specifying its name as follow : # View a single RColorBrewer palette by specifying its nameĭ(n = 8, name = 'Dark2')īrewer.pal(n = 8, name = "Dark2") # "#1B9E77" "#D95F02" "#7570B3" "#E7298A" "#66A61E" "#E6AB02" "#A6761D" To display only colorblind-friendly brewer palettes, use this R code: (colorblindFriendly = TRUE) colorblindFriendly: if TRUE, display only colorblind friendly palettes.select: A list of palette names to display.Allowed values are one of: “div”, “qual”, “seq”, or “all”. name: A palette name from the lists above.n: Number of different colors in the palette, minimum 3, maximum depending on palette.Display a single RColorBrewer paletteĭ(n = NULL, type = "all", select = NULL, Return the hexadecimal color specification The RColorBrewer package include also three important functions: # 1. The diverging palettes are : BrBG, PiYG, PRGn, PuOr, RdBu, RdGy, RdYlBu, RdYlGn, Spectral Diverging palettes (third list of colors), which put equal emphasis on mid-range critical values and extremes at both ends of the data range.The palettes names are : Accent, Dark2, Paired, Pastel1, Pastel2, Set1, Set2, Set3. They not imply magnitude differences between groups. Qualitative palettes (second list of colors), which are best suited to represent nominal or categorical data.The palettes names are : Blues, BuGn, BuPu, GnBu, Greens, Greys, Oranges, OrRd, PuBu, PuBuGn, PuRd, Purples, RdPu, Reds, YlGn, YlGnBu YlOrBr, YlOrRd.
Sequential palettes (first list of colors), which are suited to ordered data that progress from low to high (gradient).
