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) using the ggplot2 package with the pr
The scatterplot uses points, but were we instead to draw lines we would get a line plot. If we used 【bars】, we’d get a bar plot. Neither of those examples makes sense for this data, but we could still draw them, as in Figure 3.2. In ggplot2 we can produce many plots that ...

这个ggfree包虽然口号很大,不过还处于活跃的开发之中,最终能不能实现口号我们以后再看看,现而今,实现的并不多,了解一个包,从看NAMESPACE开始: 从中我们可以看到,为什么画进化树这么方便,原来作者专门针对phyloLayout的image, lines, points和text的方法,points打点,lines画线,text打文本,image画热图,你用的这些都被...
在ggplot2中,可以使用点图(geom_point)来给线图(geom_line)添加图例。要实现这个目标,可以使用scale_color_manual函数来手动设置线和点的颜色,并使用guide...
