在直方图上添加多个垂直线(vline)可以用于标记特定的数值或者阈值。下面是使用ggplot2在直方图上添加多个vline的步骤: 首先,确保已经安装了ggplot2包。如果没有安装,可以使用以下命令进行安装: 代码语言:txt 复制 install.packages("ggplot2") 导入ggplot2包: 代码语言:txt 复制 library(ggplot2) 准备数据。假设我...
dff %>% ggplot(aes(value,ID))+ geom_stripped_rows(odd="grey90",xfrom =-0.5, xto =9.5)+ geom_boxplot(aes(color=type),position = position_dodge(0.5), width=0.5,outliers = FALSE)+ geom_text(data=dff %>% select(1,p.adj) %>% distinct(), aes(x=8.2,y=ID,label=p.adj),size...
add labels to a horizontal column plot (stacked by default) ggplot(data = df, aes(x2, x1, group = grp)) + geom_col(aes(fill = grp), width=0.5) + geom_hline(yintercept = 0) + geom_text( aes(label = grp), position = position...

ggtitle("Temperatures in Chicago\nfrom 1997 to 2001") + theme(plot.title = element_text(lineheight = .8, size = 16)) 调整图例 我们将根据季节类别对数据进行颜色编码。或者用更通俗的说法:我们把季节的变化映射到色彩上。ggplot2的一个优点是,当将变量映射到美学时,它会默认添加一个图例。你可以看到...

qplot()类似于R基本绘图函数plot(),可以快速绘制常见的几种图形:散点图、箱线图、 小提琴图、直方图以及密度曲线图。其绘图格式为: qplot(x, y=NULL, data, geom="auto") 1. 其中: x,y: 根据需要绘制的图形使用; data:数据集; geom:几何图形,变量x,y同时指定的话默认为散点图,只指定x的话默认为直方...
