在`ggplot2`中向散点图添加水平线,可以通过`geom_hline()`函数实现。这个函数允许你在绘制的图形上添加一条或多条水平线。 ### 基础概念 `geom_hline()`是`ggpl...

因为我就发现啊,有些函数的用途即使人家给我用文字解释了,我还是蒙圈。比如:jitter()这个函数,R给的解释是:Add a small amount of noise to a numeric vector.每个单词我都认识,可对不起R,我还是不懂!所以呢,我就进入例子去理解。例子如下: rep(0,7) [1] 0 0 0 0 0 0 0 > jitter(rep(0,7)) [...

My preferred use of it is to prepare the plot, add horizontal lines and then plot the bars. However, when executed as shown below, R produces duplicated plots, which is not visually appealing. To create an equivalent normal plot, I searched forplot(NULL, xlim=c(1,2), ylim=c(3,5),...
