你如何制作x-lab标签斜体而不是y-lab标签呢？(在R中)

Question

你如何制作x-lab标签斜体而不是y-lab标签呢？我能找到的唯一命令(font.lab = 3)使x-lab和y-lab标记为斜体.我在R中创建了在x和y轴上具有特定名称的条形图.

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")

这是一个情节调用:
