Try 

library(ggplot2)
qplot(mpg, wt, data=mtcars, xlab = "",  ylab = bquote(mu~(E ~m^-2~s^-1)),
geom="line") 

(thanks to Baptiste and David in 
<http://r.789695.n4.nabble.com/How-to-plot-an-expression-label-with-variable-text-td2341465.html#a2341504>
)

And please always use reproducible code for posting as above; your code had
the data set missing, which was totally irrelevant anyway, and ggplot2 was
missing.
