[R] percent sign in plot annotation

I would like to annotate a graph with the expression 'alpha = 5%' (the  
alpha should be displayed as the greek letter).
I tried

> text(1,1,expression(alpha == 5%))

which gives a syntax error.
escaping the percent sign (\%) or doubling (%%) does not help.
What do I do?
