在geom_text中大致相等 [英] Plot approximately equal in geom_text
问题描述
在使用 geom_text
插入的文本之前,我不知道如何放大约等于符号。这可以工作:
pre $ g $ p $ ggplot(data.frame(x = 1:2,y = 1:2),aes(x = x,y = y))+ geom_point()+
geom_text(aes(label =10 ^ 10,x = 1.5,y = 1.5),parse = T)
如果我在文本之前放置%~~%
ggplot(data.frame(x = 1:2,y = 1:2),aes(x = x,y = y))+ geom_point )+
geom_text(aes(label =%~~%10 ^ 10,x = 1.5,y = 1.5),parse = T)
它返回一个错误:意外SPECIAL%~~%
我发现了几个相关的问题,但无法应用给出的建议。我使用包ggplot2_0.9.2.1。 Package grDevices也被加载。
它可以在等式左边的网站上使用。这也可以是 NULL
。
ggplot(data.frame(x = 1:2,y = 1:2),aes(x = x,y = y))+ geom_point()+
geom_text(aes(label =NULL%~~%10 ^ 10,x = 1.5,y = 1.5),parse = T)
I cannot realize how to put approximately equal symbol before the text inserted with geom_text
. This works:
ggplot(data.frame(x=1:2, y=1:2), aes(x=x,y=y)) + geom_point() +
geom_text(aes(label="10^10", x=1.5, y=1.5), parse=T)
If I put %~~%
before the text
ggplot(data.frame(x=1:2, y=1:2), aes(x=x,y=y)) + geom_point() +
geom_text(aes(label="%~~%10^10", x=1.5, y=1.5), parse=T)
it returns an error: unexpected SPECIAL %~~%
I found several related questions but could not apply the given advices. I use package ggplot2_0.9.2.1. Package grDevices is also loaded.
It will work with something on the left-hand site of the equation. This could also be NULL
.
ggplot(data.frame(x=1:2, y=1:2), aes(x=x,y=y)) + geom_point() +
geom_text(aes(label="NULL%~~%10^10", x=1.5, y=1.5), parse=T)
