各省消费项目均值条形图

省份过多,各省的名称均不能全部显示

barplot(apply(data,1,mean))#按行做均值条形图

将横轴左边旋转90度,各省的名称均可显示

barplot(apply(data,1,mean),las=3)#按行做均值条形图

利用ggplot2包作图较为美观

data %>%
  mutate(Average_Consumption = rowMeans(select(., -1), na.rm = TRUE)) %>% 
  ggplot(aes(x = reorder(row.names(data), -Average_Consumption), y = Average_Consumption)) +
  geom_bar(stat = "identity", position = position_dodge(), colour = "black", fill = "steelblue") +
  labs(title = "各省消费项目均值条形图", x = "", y = "均值") +
  theme_minimal() +
  theme(axis.text.x = element_text(angle = 90, hjust = 1)) 

各消费项目均值条形图

按消费项目做均值图条形图

barplot(apply(data,2,mean))#按列做均值图条形图

对不同项目的条形添加不同颜色

 barplot(apply(data,2,mean),col=1:8) #按列做彩色均值图条形图

去掉食品列后的数据按列做均值条形图

barplot(apply(data[,2:8],2,mean))

按消费项目做中位数条形图

barplot(apply(data,2,median))

利用ggplot作均值条形图

data %>% summarise(across(everything(), mean, na.rm = TRUE)) %>% 
  pivot_longer(cols = everything(), names_to = "Consumption_Type", values_to = "Average") %>% 
  mutate(
    Consumption_Type=factor(Consumption_Type,level=c('食品','衣着','设备','医疗','交通','教育','居住','杂项')),
  ) %>% 
  ggplot(aes(x = Consumption_Type, y = Average, fill = Consumption_Type)) +
  geom_bar(stat = "identity", position = position_dodge(), colour = "black") +
  theme_minimal() +
  labs(title = "各消费项目均值条形图", x = "类别", y = "均值",fill = "消费种类")
Warning: There was 1 warning in `summarise()`.
ℹ In argument: `across(everything(), mean, na.rm = TRUE)`.
Caused by warning:
! The `...` argument of `across()` is deprecated as of dplyr 1.1.0.
Supply arguments directly to `.fns` through an anonymous function instead.

  # Previously
  across(a:b, mean, na.rm = TRUE)

  # Now
  across(a:b, \(x) mean(x, na.rm = TRUE))

使各条形的颜色相同

data %>% summarise(across(everything(), mean, na.rm = TRUE)) %>% 
  pivot_longer(cols = everything(), names_to = "Consumption_Type", values_to = "Average") %>% 
  mutate(
    Consumption_Type=factor(Consumption_Type,level=c('食品','衣着','设备','医疗','交通','教育','居住','杂项')),
  ) %>% 
  ggplot(aes(x = Consumption_Type, y = Average)) +
  geom_bar(stat = "identity", position = position_dodge(), colour = "black", fill = "steelblue") +
  theme_minimal() +
  labs(title = "各消费项目均值条形图", x = "类别", y = "均值")

各消费项目箱线图

boxplot函数直接作箱线图,默认每个变量(列)作一个箱线,并将全部变量的箱线在同一个图中展示。

boxplot(data)#按列做箱线图

boxplot(data,horizontal=T,las=1)#箱线图中图形按水平放置

利用ggplot函数作箱线图,需要对数据转化为长结果数据

data %>% pivot_longer(cols = 1:8, names_to = "Consumption_Type", values_to = "Value") %>% 
  mutate(
    Consumption_Type=factor(Consumption_Type,level=c('食品','衣着','设备','医疗','交通','教育','居住','杂项')),
  ) %>% 
  ggplot(aes(x = Consumption_Type, y = Value)) +
  geom_boxplot() +
  labs(title = "各消费项目箱线图", x = "", y = "消费水平") +
  theme_minimal() #  + coord_flip() 

各消费项目星相图

stars(data)       #具有图例的360度星相图

增加 key.loc=c()用于指定星相图图例的位置

stars(data,key.loc=c(17,7))       #具有图例的360度星相图

draw.segments=T在stars( ) 函数中尤其有用,表示允许绘制线段,允许为不同线段指定颜色

stars(data,draw.segments=T,key.loc=c(17,7))#具有图例的360度彩色圆形星相图

full=F指定星相图为半图(即180度);draw.segments=T,key.loc=c(17,7))表示星相图为彩色并指定图例位置

stars(data,full=F,draw.segments=T,key.loc=c(17,7))#具有图例的180度彩色圆形星相图

各消费项目脸谱图

aplpack::faces(data)   #根据数据画出脸谱图

effect of variables:
 modified item       Var   
 "height of face   " "食品"
 "width of face    " "衣着"

ggplot2的扩展包ggiraphExtra能作雷达图

data[c(1,9,19,28,29,30),] %>% 
  mutate(省份=rownames(.)) %>% 
  ggRadar(aes(group = 省份)) 

各消费项目调和曲线图

clr=5指定使用第5种颜色来绘制曲线, ymax=6设定了y轴最大值

andrews::andrews(data,clr=5,ymax=6)  #使用data数据作调和曲线图

data[c(1,9,19,28,29,30)表示指定用第1,9,19,28,29,30个观测的多元数据做调和曲线图

andrews::andrews(data[c(1,9,19,28,29,30),],clr=5,ymax=6)  #选择第1,9,19,28,29,30个观测的多元数据做调和曲线图

改进调和曲线图,且用不同的颜色和线段表示不同数据并增加了图例

msa.andrews(data)    #绘制调和曲线图

选择第1,9,19,28,29,30个观测的多元数据作改进后的调和曲线图,图中用不同的颜色和线段表达了不同变量,使数据更清晰易读

msa.andrews(data[c(1,9,19,28,29,30),])
