Question

我正在尝试使用以下数据创建带有错误栏的绘图（最后是数据帧的输入）。我想为每个“loc”的“est A”和“est B”变量创建错误栏，但是我无法找出融合/转换数据的正确方法，这样每个“loc”就会有两行几列。

即。我想将数据帧转换为

loc est value lb ub

a A 0.56 0.26 1.20

a B 0.26 0.11 0.60

b A 0.13

b B 0.03

c A

c B

ggplot(test,aes(x=Loc,y=value,color=est))+geom_point()+geom_errorbar(aes(ymax=ub,ymin=lb))

Answer 1

我调用了您的数据框数据，然后：

test <- with(Data,
   data.frame(
     Loc = rep(Loc,2),
     est = rep(c("A","B"),each=nrow(Data)),
     value = c(get("est A"),get("est B")),
     lb = c(get("A lb"),get("B lb")),
     ub = c(get("A ub"),get("B ub"))
   )
)
ggplot(test,aes(x=Loc,y=value,color=est))+geom_point()+
     geom_errorbar(aes(ymax=ub,ymin=lb))

请尽可能地使用变量名称和空格。如果你没有，你可以做到：

test <- with(Data,
   data.frame(
     Loc = rep(Loc,2),
     est = rep(c("A","B"),each=nrow(Data)),
     value = c(estA,estB),
     lb = c(Alb,Blb),
     ub = c(Aub,Bub)
   )
)
ggplot(test,aes(x=Loc,y=value,color=est))+geom_point()+
    geom_errorbar(aes(ymax=ub,ymin=lb))

Answer 2

如果您想使用reshape包，我找到了以下解决方案（假设您的数据框的变量名为w / o空格）：

head(df)

  Loc       estA        estB         Alb       Aub         Blb        Bub
1   a 0.56327093 0.261222077 0.262976608 1.2064729 0.111866194 0.60998744
2   b 0.13710987 0.036116906 0.072413817 0.2596068 0.016916967 0.07710785
3   c 0.09465147 0.038929501 0.049682119 0.1803244 0.018676127 0.08114670
4   d 0.18510306 0.034148992 0.083935852 0.4082063 0.012147149 0.09600225
5   e 0.03225662 0.007222061 0.006303808 0.1650573 0.001263808 0.04127063
6   f 0.12250992 0.075619254 0.049056208 0.3059487 0.027953280 0.20456532

test <- data.frame(cbind(melt(df[,1:3]), lb=c(df$Alb, df$Blb), ub=c(df$Aub, df$Bub)))
ggplot(test2,aes(x=Loc,y=value,color=variable)) + geom_point() + geom_errorbar(aes(ymax=ub,ymin=lb))

您只需熔化est-columns并将熔化的数据框与链接的下限/上限列绑定。

ggplot和错误栏
