To begin, let’s create a basic scatter plot usingqplot()with the default point size. We’ll utilize a sample dataset for demonstration. library(ggplot2)df<-data.frame(x=c(1,2,3,4,5),y=c(10,15,8,20,12))qplot(x=x,y=y,data=df,main="Basic Scatter Plot",xlab="X Axis",ylab...
Example 2: Change Size of Plots in ggplot2 Grid Layout This example explains how to draw a grid ofggplot2 plotswith different sizes. In order to use the functions of the ggplot2 package, we first need to install and load ggplot2: install.packages("ggplot2")# Install ggplot2 packagelibrar...
ggp<-ggplot(data, aes(x, y, col=factor(x)))+# Create default ggplot2 plotgeom_point(size=10)ggp# Draw default ggplot2 plot After running the previously shown R programming syntax the scatterplot shown in Figure 1 has been created. ...
ggplot(data = df, aes(x = DATE, y = TAVG, color = TAVG))+geom_point(size = 7, alpha = 0.8)+geom_smooth(color = "white", se = FALSE)+scale_color_gradient(name = "ºC", low = datacamp_colors$blue, high = datacamp_colors$pink)+ggtitle("Historical air temperature trend in ...

2 计算脆弱性:用网络中节点的最大脆弱性表示。 3 组成稳定性:微生物群落结构随时间的变化。 4 节点持久性:为节点在网络中连续多年存在的百分比。 5 负相关边数的比例:负相关的比例越高网络越稳定。 这里主要介绍前四种的计算过程,...

請注意上圖中的差異,以及點的大小是如何增加的。 如果你使用qplot()函式繪製散點圖,我們可以使用size引數設定點的大小。請看下面的程式碼。 qplot(v1,v2,size=I(5)) 在使用ggplot()函式時,也可以應用同樣的引數。
