Renaming columns in ggplot2 with "+" and "-" at the end of plot construction

I'm trying to rename the columns in my bar graph from "nCO2" and "pCO2" to "-CO2" and "+CO2". I decided to do it at the end of the plot construction rather than renaming the elements at the beginning, since the + and - interfered with the data transformations. How can I rename these columns after the construction of my bar plot?

structure(list(CO2_stacks = c("nCO2", "nCO2", "nCO2", "nCO2", 
"nCO2", "nCO2", "pCO2", "pCO2", "pCO2", "pCO2", "pCO2", "pCO2"
), count = c(3.3, 3.2, 3, 3.5, 3.3, 3.2, 4, 3.9, 4.2, 4.1, 4.3, 
4)), class = "data.frame", row.names = c(NA, -12L))

Plotting:

ggplot(stackoverflow, mapping = aes(CO2_stacks, count)) + geom_boxplot()

Try this:

library(ggplot2)

ggplot(stackoverflow, mapping = aes(CO2_stacks, count)) +
  geom_boxplot()+
  scale_x_discrete(labels= c("nCO2"="-CO2","pCO2"="+CO2"))

Output:
