The returned palette contains the corresponding gray colors. This palette is used in barplot.default. grey.colors is an alias for gray.colors. See Also. gray, rainbow, palette. Examples # NOT RUN { require(graphics) pie(rep(1, 12), col = gray.colors(12)) barplot(1:12, col = gray.colors(12)) # }
The colors on boxplot look good. However, sometime you might want to use color palettes available from RColorbrewer package. ggplot2 has two functions available for using color palettes in ggplot2, one is scale_fill_brewer() and scale_color_brewer().
This was essentially for backwards-compatibility, particularly of documentation. If a figure uses col = 2 and the accompanying text refers to it as red, it should not be completely wrong with the new palette. There are a few color palettes built into base R, but probably the most popular come from the RColorBrewer and viridis packages. You can install both from CRAN.

For example, here’s the scatterplot function from the car package plotting the iris data with ggplot2 colors.
When “OK” is selected, the color palette will be saved in the R session. To return 7 hex color codes from the selected palette: pal <- choose_palette() pal(7) [NOTE: These values are not saved if you don’t save the session] Option 1 If you don’t need to control which colors are associated with each level of a variable:

The color palettes available in the RColorBrewer package are described here : color in R. # Box plot bp + scale_fill_brewer(palette="Dark2") # Scatter plot sp + scale_color_brewer(palette="Dark2") The available color palettes in the RColorBrewer package are : A guide to using colors in R. There are three types of R colors: hexadecimal colors (#rrggbb) or (#rrggbbaa) aa being alpha (how opaque the color is) named colors e.g.

R color cheatsheet Finding a good color scheme for presenting data can be challenging. This color cheatsheet will help! R uses hexadecimal to represent colors Hexadecimal is a base-16 number system used to describe color. R base color palettes: rainbow, heat.colors, cm.colors. Note that, the “rainbow” and “heat” color palettes are less perceptually uniform compared to the other color scales.
