【问题描述】:
我正在尝试在 x 或 y 标签中使用以下表达式绘制图形: 例如
qplot(x=rnorm(20), y=rnorm(20))+
ylab("Per mil--> [\u2030]")+ #this works for me
xlab(expression(paste(delta,""^"13","C [\u2030]"))) #this doesn't work on my Mac and shows: d13C [ U+2030>], where d13C is correctly shown, but the sign for per mil not; on Windows this expression was working
我希望你能帮助我。谢谢!
