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 0.5ToothGrowth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)
