我用下面的數據幀創造GGPLOT2深度圖:位置上的誤差棒翻轉軸閃避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))
我用這個代碼GGPLOT2創建一個情節,但位置閃避似乎並沒有像在線條和點上使用錯誤條一樣工作。我需要我的錯誤條來貫穿我的觀點(即讓他們躲避相同的數量)。謝謝你的幫助。
