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),...
更简洁更准确的做法应该是先对这些点进行标签，然后设置每个标签的color, shape以及linetype，代码如下：p...
