以45度角在R中的方框图中插入标签？

在boxplot（）命令中是否有任何方法可以将标签旋转45度

---

我意识到las=2命令将它们旋转为垂直于x轴，但我希望它们为45度

以下内容如何：

# Some sample data
x <- list(x = rnorm(100, 2), y = rnorm(100, 4));
# Plot without x axis
boxplot(x, xaxt = "n");
# Add axis labels rotated by 45 degrees
text(seq_along(x), par("usr")[3] - 0.5, labels = names(x), srt = 45, adj = 1, xpd = TRUE);
