R plot: how to write superscript expression with greek letters?

Question

I am try to write "2 ^-ΔΔC_T" in a Y axes in a graph. Please, note the letter "T" is subscripted in the expression "-ΔΔC_T". This is the closest that I could do:

   plot + ylab(expression(paste("2"^{-ddC[T]})))

Do you have any better suggestion?

Thanks

Answer 1

Maybe something like this...

plot(1, ylab=expression(2^{-Delta* Delta*C[T]}))

which produces...
