上标"^ oC"；在ggplot的ylab中- [英] Superscript "^oC" in ylab in ggplot -

问题描述

试图绘制"^ oC"，但不断出现错误:错误:" ggplot中出现意外的'^'但是，如果我放置"R ^ {o} C"是可行的.请参阅下面的代码段.第一个代码不起作用，第二个代码不起作用，但是对于ylab中的"R"无效.

Trying to plot "^oC" but keep getting an error: "Error: unexpected '^' in "ggplot" However if I place "R^{o}C" is works. See code snippets below. The first code does not work the second works but not useful with "R" in ylab.

ggplot(MD15，aes(DateTime，Temp/100))+ geom_point(position ="jitter")+ labs(title ="Phase 3-March 2012")+ ylab(expression(Temp〜(〜^ {o}〜C)))

ggplot(MD15，aes(DateTime，Temp/100))+ geom_point(position ="jitter")+ labs(title ="Phase 3-March 2012")+ ylab(expression(Temp〜(R^ {o}〜C)))

环顾四周并尝试了一些建议，但没有任何效果.如果已回答此问题，将不胜感激.谢谢！文斯

Looked around and tried several suggestions but none work. If this has been answered a link would be appreciated. Thanks! Vince
