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)) [...

线(line,vline,abline,hline,stat_function等):一般是基于函数来处理位置 射(segment):特征是指定位置有xend和yend,表示射线方向 面(tile, rect):这类一般有xmax,xmin,ymax,ymin指定位置 棒(boxplot,bin,bar,histogram):往往是二维或一维变量,具有width属性 带(ribbon,smooth):透明是特征是透明的fill 补:包...
It is possible to add lines over grouped bars. In this example, there are actually four lines (one for each entry forhline), but it looks like two, because they are drawn on top of each other. I don’t think it’s possible to avoid this, but it doesn’t cause any problems. ...

Example 1: Add Line to ggplot2 Barplot Example 1 illustrates how to overlay a line on top of a ggplot2 barchart. To achieve this, we can apply the geom_line function as shown below. Note that we are multiplying the variable that we want to overlay as a line (i.e. responses) by ...
