Continuous colors The graph can be colored according to the values of a continuous variable using the functions : scale_color_gradient(), scale_fill_gradient() for sequential gradients between two colors scale_color_gradient2(), scale_fill_gradient2() for diverging gradients scale_color_gradientn...

Change a ggplot gradient color(also known as continuous color). To create a gradient color in ggplot2, a continuous variable is mapped to the optionscolororfill. There are three different types of function to modify the default ggplot2 gradient color, includingscale_color_gradient(),scale_color...

Let’s say we want to study the relationship between 2 numeric variables. It is possible to cut on of them in different bins, and to use the created groups to build aboxplot. Here, the numeric variable calledcaratfrom thediamondsdataset in cut in 0.5 length bins thanks to thecut_widthfu...
p <- ggplot(data=gapminder,mapping = aes(x = gdpPercap,y = lifeExp,color = continent)) 程序中仅指定了将大洲映射到颜色维, 并不具体指定所用的颜色。 作带有局部多项式曲线拟合的散点图: p + geom_point() +geom_smooth(method="loess") +scale_x_log10(labels=scales::dollar) ...
that interface includes functions specifically for ggplot use, with a syntax such as scale_color_paletteer_d(“nord::aurora”). Here nord is the original palette package name, aurora is the specific palette name, and the _d signifies that this palette is for discreet values (not continuous)...
