[R] greek letters for labelling axes

[Samuel Kemp]

Hi,

Does anyone have any ideas on how to show greek letters on the x and y axes?

I have tried

 > plot(x,y, xlab=expression(delta), ylab=expression(gamma))

but the output on the x-axis is "d" and on the y-axis it is "g".

Any help will be very much appreciated.

Cheers,

Sam.
