[R] text(): combine expression and line break

[Bert Gunter]

Try this:
 plot(1,type="n", xaxt='n', yaxt='n', ann=FALSE)
 text(1,1,labels=expression(atop(sigma,"(log scale, m)")),cex = 2)

You can add extra blank characters to align the text like this:

 plot(1,type="n", xaxt='n', yaxt='n', ann=FALSE)
text(1,1,labels=expression(atop(sigma,phantom("WWWWW")~"(log scale,
m)")),cex = 2)

I would not be surprised if there are more elegant ways to do it, though.

Cheers,
Bert
