我是 R 和一般編程的新手，我有一個與此類似的資料框，但有更多行：
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 創建一個折線圖，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！

另一種解決方案堆疊條形圖：
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)
繪制情節：
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：

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))
