首先，代码中的第一部分，即TernaryPlot()函数，就是Ternary包绘制三元图的基本函数；我们通过修改其中各项参数，从而修改最终成图中各个部分的属性。其中，函数的第一行，也就是alab开头的这一行，表示三角形三条边分别要显示的字符，也就是“标注”；lab.col则表示三角形中三条边对应的坐标轴的文字标注...
Now, we can use the geom_line & geom_point functions to draw a ggplot2 graph with lines and points: ggplot(data, aes(x, y))+# Draw ggplot2 plotgeom_line()+geom_point() As shown in Figure 1, we created a line and point plot (i.e. a graph where the lines connect the points...
