R中图形的线图？

我在R中有一个csv，它有下表：

df1 <- data.frame(
        "Pool 1" = c("F1a", "R1a", "F2a", "R2a"),
        "Start Pool 1" = c("10", "20", "25", "35"), 
        "Pool 2" = c("F1b", "R1b", "F2b", "R2b"),
        "Start Pool 2" = c("15", "21", "23", "35"), 
        stringsAsFactors = F,check.names=FALSE)

---

df1似乎池2的标签是错误的，应该是R1b

如果您不想使用任何软件包，并且只有两行，您可以通过使用
plot（NULL…
）指定空白绘图来缓慢构建它，然后将一行放在
y=1
，另一行放在
y=2
上，并根据这些坐标添加点、文本：

plot(NULL,xlim=c(10,35),ylim=c(0,3),xaxt="n",yaxt="n",
bty="n",xlab="",ylab="")
abline(h=1:2,col="#c0fefc")
points(x = df1[,"Start Pool 1"], y = rep(2,nrow(df1)),
pch=20,cex=2,col="#77acf1")
text(x = df1[,"Start Pool 1"], y = rep(2.5,nrow(df1)),
labels = df1[,"Pool 1"])
points(x = df1[,"Start Pool 2"], y = rep(1,nrow(df1)),
pch=20,cex=2,col="#77acf1")
text(x = df1[,"Start Pool 2"], y = rep(1.5,nrow(df1)),
labels = df1[,"Pool 2"])
axis(side=2,at=1:2,labels=c("Pool2","Pool1"),las=2,col=NA,col.ticks = 1)


否则请使用
ggplot2
：

df = data.frame(
       label = c(df1[,"Pool 1"],df1[,"Pool 2"]),
       value = c(df1[,"Start Pool 1"],df1[,"Start Pool 2"]),
       pool = rep(c("Pool1","Pool2"),each=nrow(df1))
       )

ggplot(df,aes(x=value,y=pool,label=label)) + 
geom_point(size=4,col="#77acf1") + 
geom_text(nudge_y=0.2) + 
theme_minimal() + 
xlab("") + ylab("") +
theme(panel.grid.major.x = element_blank(),
axis.ticks.x = element_blank(),
axis.text.x = element_blank())

请您提供更详细的信息好吗？例如，您能否澄清您希望的
x轴是什么。？
