[R] Bold Face in Plot

Dear all, I am trying to plot some text in bold face which works fine: plot(0:1,0:1,type="n") text(x=0.5, y=0.5, labels=expression(bold("the-actual-string"))) Now when I try to do the following, the displayed text reads thestring: thestring <- "the-actual-string" plot(0:1,0:1,type="n") text(x=0
