R：如何將普通箱線圖與分組箱線圖結合起來

Question

我正在嘗試將分組箱線圖添加到只有一組的箱線圖中。 我已經做到了，但問題是我無法為只有一組的箱線圖命名。 它根本沒有顯示。 當您的箱線圖沒有不同的組時，arguments“名稱”和“名稱”似乎不起作用。

boxplot(Daten$NV,
        boxwex = 0.6, at = 1:1 - 0.2,col = "yellow",
        name = "Gesamtstichprobe",
        main = "Guinea Pigs' Tooth Growth",
        xlab = "Vitamin C dose mg",
        ylab = "tooth length",
        xlim = c(0.5, 3.5), ylim = c(0, 7), yaxs = "i")
boxplot(Daten$NV ~ Daten$CVKGruppe, add = TRUE,
        boxwex = 0.3, at = 1:3 + 0.3, col = "orange")

Answer 1

你可以這樣做：

boxplot( Daten$NV,
        boxwex = 0.6, at = 1:1 - 0.2, col = "yellow",
        name = "Gesamtstichprobe",
        main = "Guinea Pigs' Tooth Growth",
        xlab = "Vitamin C dose mg",
        ylab = "tooth length",
        xlim = c(0.5, 3.5), ylim = c(0, 7), yaxs = "i", xaxt = "n")
axis(1, at = 0.8, labels = "Total")
boxplot(Daten$NV ~ Daten$CVKGruppe, add = TRUE,
        boxwex = 0.3, at = 1:3 + 0.3, col = "orange")

                  each = 50))
