位置上的误差棒翻转轴闪避GGPLOT2

我用下面的数据帧创造GGPLOT2深度图：位置上的误差棒翻转轴闪避GGPLOT2

TTTTOM<- data.frame(Treatment=c("Mineral", "Mineral", "Mineral", "OM", "OM", "OM", "Veg", "Veg", "Veg"), Depth2=c(-7.5, -4.5, -1.5, -7.5, -4.5, -1.5, -7.5, -4.5, -1.5), mean=c(2.83, 3.33, 3.16, 9.16, 11.17, 11.67, 4.83, 5, 5.17), se=c(0.7, 1.12, 0.65, 2.41, 3.28, 3.12, 1.83, 1.71, 0.95))

我用这个代码GGPLOT2创建一个情节，但位置闪避似乎并没有像在线条和点上使用错误条一样工作。我需要我的错误条来贯穿我的观点（即让他们躲避相同的数量）。谢谢你的帮助。

pd <- position_dodge(0.3) 
ggplot(TTTTOM, aes(x=Depth2, y=mean, linetype=Treatment)) + 
    geom_line(aes(linetype=Treatment), colour="black", size=0.75, position=pd) + 
    geom_errorbar(aes(ymin=mean-se, ymax=mean+se), linetype=1, colour="black", width=.1, position=pd) + 
    geom_point(colour="black",shape=16, size=2.0, position=pd) + 
    scale_linetype_manual(values=c(1, 2, 4), labels=c("Organic", "Mineral", "Vegetated"))+ 
    geom_vline(aes(xintercept=0), linetype="dashed")+ 
    theme(legend.position="none", 
    axis.title.x=element_text(size=18, margin=margin(10,0,0,0)), 
    legend.title=element_blank(), 
    legend.text=element_text(size=18), 
    legend.key.width=unit(2,"line"), 
    axis.text=element_text(size=18), 
    axis.title.y=element_text(size=16, margin=margin(0,10,0,0)), 
    plot.margin = unit(c(.25, .25, .25, .25), "in"))+ 
    labs(x=paste("Distance from \n sediment surface (cm)"), y="% Total OM") + 
    expand_limits(x=c(-10,0))+ 
    coord_flip()

您的来电geom_errorbar（）需要一个组参数;在这种情况下，组=治疗：

pd <- position_dodge(.3) 

ggplot(TTTTOM, aes(x=Depth2, y=mean, linetype=Treatment)) + 
    geom_line(aes(linetype=Treatment), colour="black", size=0.75, position=pd) + 
    geom_errorbar(aes(ymin=mean-se, ymax=mean+se, group=Treatment), 
      linetype=1, colour="black", width=.1, position=pd) + 
    geom_point(colour="black",shape=16, size=2.0, position=pd) + 
    scale_linetype_manual(values=c(1, 2, 4), labels=c("Organic", "Mineral", "Vegetated"))+ 
    geom_vline(aes(xintercept=0), linetype="dashed")+ 
    theme(legend.position="none", 
     axis.title.x=element_text(size=18, margin=margin(10,0,0,0)), 
     legend.title=element_blank(), 
     legend.text=element_text(size=18), 
     legend.key.width=unit(2,"line"), 
     axis.text=element_text(size=18), 
     axis.title.y=element_text(size=16, margin=margin(0,10,0,0)), 
     plot.margin = unit(c(.25, .25, .25, .25), "in"))+ 
    labs(x=paste("Distance from \n sediment surface (cm)"), y="% Total OM") + 
    expand_limits(x=c(-10,0))+ 
    coord_flip()

输出：
