连续映射的实现主要有scale_fill_gradient() 【默认渐变着色】;scale_fill_distiller() 【调色板着色】,这里仅介绍渐变着色。 3.21 渐变着色 scale_fill_gradient() 【双色渐变,参数:low, high】 scale_fill_gradient2() 【三色渐变,参数:low, mid, high】 scale_fill_gradientn() 【n色渐变,参数:colours/co...

使用scale_fill_gradientn()函数为不同的数值范围设置不同的颜色。scale_fill_gradientn()允许你定义多个断点并为每个断点指定颜色。 使用ggplot2创建heatmap: 使用ggplot2包中的ggplot()和geom_tile()函数来创建heatmap。 将颜色设置应用于heatmap: 在aes()函数中设置fill映射,并在scale_fill_gradientn()中定义...
