首先确保安装ggplot2包(如果尚未安装): # 安装ggplot2包(若未安装,请先取消注释)# install.packages("ggplot2")library(ggplot2)# 使用ggplot2绘制散点图ggplot(data,aes(x=x,y=y,color=group))+geom_point(size=3)+labs(title="Ggplot2 Plot Color by Group",x="X-axis",y="Y-axis")+scale_color...
We present the top R color palette to customize graphics generated by either the ggplot2 package or by the R base functions. The main points are summarized as follow. Create a basic ggplot. Map thecolorargument to a factor or grouping variable. p <- ggplot(iris, aes(Sepal.Length, Sepal....
