In addition, you could have a look at the other posts on my website. I have released numerous tutorials about similar topics such as graphics in R, plot legends, and ggplot2 already. Change Font Size of ggplot2 Plot Change Font & Item Size in Base R Plot Legend Change Legend Size in ...
也可以用以下函数调节分组的形状,颜色,大小 • scale_shape_manual() : to change point shapes• scale_color_manual() : to change point colors• scale_size_manual() : to change the size of points ggplot(mtcars, aes(x=wt, y=mpg, group=cyl)) + geom_point(aes(shape=cyl, color=cy...

火山图(Volcano Plot)常用于展示基因表达差异的分布,横坐标常为Fold change(倍数),越偏离中心差异倍数越大;纵坐标为P value(P值),值越大差异越显著。得名原因也许是因为结果图像火山吧 一 载入R函数包及数据集 代码语言:javascript 代码运行次数:0 运行 ...

上面的命令先将变量 Treat 映射为颜色和线型,再画出 3 种治疗方式下的体重改变量 wt.change 的密度曲线,如上图所示。 除了直方图和密度曲线图,箱线图也经常用于展示数值型变量的分布,尤其多用于各组之间分布的比较。例如: p4 <- ggplot(anorexia, aes(x= Treat, y = wt.change)) + geom_boxplot() + ...
2.1 如何更改图例标题(How to Change the Legend Title) 现在让我们更改图例标题。我们有两个图例,颜色和大小。大小基于连续变量,而颜色基于分类(离散)变量。有3种方法可以更改图例标题。 方法1:使用 labs() library(ggplot2)# Base Plotgg<-ggplot(midwest,aes(x=area,y=poptotal))+geom_point(aes(col=state...
