I want to add brackets [] around an expression in ggplot. In my code I want the brackets around the "O2" expression.
I have tried this code for naming the y axis of my plot. But it does not work, where am I going wrong here?
scale_y_continuous(name = bquote('[O'[2], ']'[crit]~(mg~O[2]/L^-'1'))
I get the error "Error in as.environment(where) : invalid object for ‘as.environment’"
Thank you in advance.
>Solution :
The bquote can be fixed i.e.
... +
scale_y_continuous(name = bquote("["*O[2]*"]"[crit]~(mg~O[2]/L^-1)))
-testing
plot(1, 1, main = bquote("["*O[2]*"]"[crit]~(mg~O[2]/L^-1)))
-output
