R Graphics Cookbook 第七章 Annotations 整理而来。 7.1.添加文本注释 用annotate()和text geom(文字对象):如下: annotate 里面用"text"类型,然后x,y分别代表文本的位置。label的内容是文本的实际内容。 annotate 中的类型 text 文本 rect 阴影矩形 segment 线段 library(ggplot2)# 创建一个图层p<-ggplot(faithful...
Have a look at the following R code and the resulting graphic: ggp+# Add text element to plotannotate("text", x=1.5, y=2.2, label="Text No. 1") As shown in Figure 2, the previous syntax has created a ggplot2 plot with one text element in the middle of the plot. ...

Example 1: Annotate Bold Text Element to ggplot2 Plot This example illustrates how to draw a bold text element to a ggplot2 graph in R. For this, we have to specify the fontface argument within the annotate function to be equal to “bold”: ...
ggcoverage can generate publication-quality plots and users can customize the plots with ggplot2. In addition, ggcoverage supports the visualization and annotation of protein coverage. Conclusions: ggcoverage provides a flexible, programmable, efficient and user-friendly way to visualize and annotate ...
