你如何制作X-Lab Label斜体而不是Y-Lab标签？（在r）

Question

你如何只做X-Lab标签斜体而不是Y-Lab标签？唯一的 我可以找到的命令（font.lab= 3）使X-Lab和Y-Lab标签标签斜体。我在x和y轴上具有特定名称的R中创建arppots。

barplot(y, main="Main Title",
    names=c("a", "b", "c"),
    xlab="Text that I would like to be in italics",
    ylab="Text that I do NOT want to be in italics",
    font.lab=3)

.

Answer 1

 barplot(y, main="Main Title",
     names=c("a", "b", "c"),
     xlab=expression(italic("Text that I would like to be in italics")),
     ylab="Text that I do NOT want to be in italics")

.

这是一个plotmath调用：

?plotmath
