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
We make dumbbell plot by plotting points for each time point and connect them with a line for each country. In order to connect the points, we need specify which rows or countries need to be connected. We create a new variable that specifies the group corresponding to each country. library...
ggplot2包有两个绘图方法,一个是qplot,一个是ggplot方法。 qplot()函数即 quick plot(快速绘图),是R语言的plot过渡到ggplot而存在的,怕用户直接使用ggplot不习惯,当然qplot也包含了ggplot的很多思想,在使用qplot会慢慢理解ggplot的映射,分组,图层等的概念。虽然使用qplot函数也能实现大部分ggplot的功能,但是只是用qplot...

For line graphs, the data points must be grouped so that it knows which points to connect. In this case, it is simple – all points should be connected, so group=1. When more variables are used and multiple lines are drawn, the grouping for lines is usually done by variable (this is...
Extending some ggplot2 functionalities by permitting the drawing of both quantile-quantile (Q-Q) and probability-probability (P-P) points, lines, and confidence bands - aloy/qqplotr
“Geoms” (aka, geometric objects) are the geometric objects that get drawn in the data visualization; things like lines, bars, points, and tiles. Keep in mind that there are dozens of geoms in the ggplot2 system, but all of them are essentially just types of shapes that we can draw ...

(group=1),size=2,method="lm",se=FALSE)# Overriding the default grouping# The plot has a discrete scale but you want to draw lines that connect across# groups. This is the strategy used in interaction plots, profile plots, and parallel# coordinate plots, among others. For example, we ...
