Plot approximately equal in geom_text

ggplot2, r

Solution

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)

Problem

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.
