ggplot2.stripchart:使用ggplot2和R软件的简单一维散点图

介绍

ggplot2.stripchart是一个易于使用的函数(来自easyGgplot2包),使用ggplot2绘图系统和R软件生成条带图。 条形图也被称为一维散点图(或点图)。 当样本量较小时,这些图比较适用于箱型图。

加载数据

# library(devtools)
# install_github("easyGgplot2", "kassambara")
library(easyGgplot2)
# create a numeric vector
numVector<-rnorm(100)
head(numVector)
# data.frame
df <- ToothGrowth
head(df)
  len supp dose
1  4.2   VC  0.5
2 11.5   VC  0.5
3  7.3   VC  0.5
4  5.8   VC  0.5
5  6.4   VC  0.5
6 10.0   VC  0.5

ToothGrowth描述了维生素C对豚鼠牙齿生长的影响。有3个变量有60个观测值。 * [,1] len数字牙齿长度。 * [,2]补充因子补充类型(VC或OJ)。 * [,3]剂量数字以毫克为单位的剂量。

# Stripchart from a single numeric vector 
ggplot2.stripchart(data=numVector)
# Basic stripchart from the vector "len"
ggplot2.stripchart(data=df, xName='dose',yName='len')
#change dot size
ggplot2.stripchart(data=df, xName='dose',yName='len', 
                   size=3)
# Change the orientation: Horizontal stripchart
ggplot2.stripchart(data=df, xName='dose',yName='len',
                   orientation="horizontal")
# Stripchart with box plot
ggplot2.stripchart(data=df, xName='dose',yName='len',
                   addBoxplot=TRUE)
# stripchart with notched box plot
ggplot2.stripchart(data=df, xName='dose',yName='len',
                   addBoxplot=TRUE,notch=TRUE)

notch:如果为真,则制作缺口盒图。 缺口显示中间值周围的置信区间.缺口用于比较组; 如果两个盒子的缺口不重叠,这是有力的证据表明两组中位数不同。

带平均点的带状图


# Stripchart with mean point
ggplot2.stripchart(data=df, xName='dose',yName='len',
                   addMean=TRUE, meanPointShape=23, meanPointSize=4,
                   meanPointColor="black", meanPointFill="blue")
# Change the stripchart color
ggplot2.stripchart(data=df, xName='dose',yName='len',
                   colour="red")

更改条形图点的形状

# Change point shape
ggplot2.stripchart(data=df, xName='dose',yName='len',
                   shape=18)
# Change point shape
ggplot2.stripchart(data=df, xName='dose',yName='len',
                   shape=17)
