我正在嘗試使用 ggplot 在 R 中創建折線圖

Question

我是 R 和一般編程的新手，我有一個與此類似但行數更多的數據框：

yes_no <- c('Yes','No','No','Yes','Yes','No','No','No','Yes','Yes','No','Yes','No','Yes','No','Yes','No','Yes','No','Yes')
age <- c('1','1','2','3','4','5','1','2','2','3','1','5','5','5','1','4','4','2','5','3')

data<- data.frame(yes_no,age)

我正在嘗試使用 ggplot 創建折線圖，其中 x 軸是年齡，y 軸是特定年齡的“是”百分比。

我不太確定如何創建百分比

有什么建議嗎？ 謝謝你！

Answer 1

另一個解決方案堆積條形圖：

Sample data:

    yes_no<-c('Yes','No','No','Yes','Yes','No','No','No','Yes','Yes','No','Yes','No','Yes','No','Yes','No','Yes','No','Yes')
        age <- c('1','1','2','3','4','5','1','2','2','3','1','5','5','5','1','4','4','2','5','3')
        
    data<- data.frame(yes_no,age)

繪制 plot：

    ggplot(data, aes(x = factor(age), fill = factor(yes_no))) +
      geom_bar(position="fill", width = 0.7)+
 geom_text(
    aes(label=signif(..count.. / tapply(..count.., ..x.., sum)[as.character(..x..)], digits=3)),
    stat="count",
    position=position_fill(vjust=0.5)) +
      labs(x="Age", y="Percentage", title="", fill="")+
      theme_bw() +
      theme(plot.title = element_text(hjust = 0.5,  face="bold", size=20, color="black")) + 
      theme(axis.title.x = element_text(family="Times", face="bold", size=16, color="black"))+
      theme(axis.title.y = element_text(family="Times", face="bold", size=16, color="black"))+
      theme(axis.text.x = element_text( hjust = 1,  face="bold", size=14, color="black") )+
      theme(axis.text.y = element_text( hjust = 1,  face="bold", size=14, color="black") )+
      theme(plot.title = element_text(hjust = 0.5))+
      theme(legend.title = element_text(family="Times", color = "black", size = 16,face="bold"),
            legend.text = element_text(family="Times", color = "black", size = 14,face="bold"),
            legend.position="bottom",
            plot.title = element_text(hjust = 0.5))

結果：

Answer 2

data %>%
  group_by(age, yes_no) %>%
  mutate(k = n()) %>%
  ungroup(yes_no) %>%
  mutate(n = n(),
         p = 100*k/n) %>%
  unique() %>%
  ungroup() %>%
  complete(age, yes_no,
           fill = list(k = 0, n = 0, p = 0))  %>%
  ggplot(aes(x=age, y =p, group = yes_no, color = yes_no)) +
  geom_line() +
  ylim(c(0,100))
