How can I write cm yr^-1 in axis label or xlab R using ggplot2 ?

I've tried: 

xlab("Predicted dbh annual increment\n(cm yr^{-1})")

but failed.

Thanks for your help.

  • You could try something like the following `xlab(bquote("Predicted dbh annual increment (cm" ~yr^{-1}~ ")"))` – steveb Jul 03 '16 at 17:02

You can use the Unicode symbol of the minus and just do copy and paste: "⁻¹"

Or you can take a look at the shortcuts for all systems. For Linux it would be: "Ctrl+Shift+U"+"207b" for the minus and "circumflex"+"1" for the superscript one
