在stat_density_2d中删除背景可以通过调整参数来实现。stat_density_2d是ggplot2包中的一个函数,用于绘制二维密度图。要删除背景,可以使用fill参数将背景颜色设置为透明,或者使用alpha参数将背景透明度设置为0。 下面是一个示例代码,演示如何在stat_density_2d中删除背景: 代码语言:txt 复制 library(ggplot2) # 创建...

Warning message:Removed96rows containing non-finite values(stat_density2d). Using real city crime data, it actually reported removing most rows. So it worries me maybe the plot doesn't reflect the real distribution. What does it mean? Should I worry that the plot doesn't reflect the data?
可以将密度Map到Alpha比例,以便较低的值是透明的:
ggplot(rbind(data.frame(data,group="a"),data.frame(data2,group="b")),aes(x=x,y=y))+stat_density2d(geom="tile",aes(fill=group,alpha=..density..),contour=FALSE)+scale_fill_manual(values=c("a"="#FF0000","b"="#00FF00"))+geom_point()+theme_minimal()+xlim(-3.3,3.3)+ylim...

base_plot + stat_density2d(aes(alpha = ..density..), geom = "tile", contour = FALSE) Notice, however, we can no longer see the points generated from geom_point(). Finally, note that you can control the bandwidth of the density estimate. To do this, we pass x and y bandwidth ...
