I suspect that you may have to construct the legend by hand (well, by explicit
text commands anyway)
Something like this seems to work and it should not be that difficult to write
a function to handle the text commands.
plot(1:10,10:1,lty=1,type='b', lwd=2,pch='a')
text(1.4,6, label="-a- ", col="red")
text(2.5,6, label="dg1")
