Colour Gradient Scale with scale_fill_gradientn in R

Key points The scale_fill_gradientn is a powerful function of ggplot2 for data visualization customization. It is a function in the ggplot2 package that allows you to create an n-color gradient scale for fill aesthetics by specifying a vector of colors and adjusting other parameters. It is useful for customizing the color scheme of your plots by highlighting patterns, trends, or differences in your data and making your plots more appealing and informative. It can be applied to different types of plots, such as heat maps, choropleth maps, and contour plots, that use fill aesthetics to represent a numeric variable. It has several parameters that you can adjust to customize your plot further, such as the values, the space, the na.value, and the guide that controls the position, the interpolation, the missing value, and the legend of the gradient scale. It can be combined with other functions, such as RColorBrewer, to use custom color palettes or deal with missing values and outliers. Functions …
