I am playing with the source code of comparison.cloud from Ian Fellows. I want to highlight some of the text by underlining it based on some criteria:
text(x1,y1,words[i],cex=size[i],offset=0,srt=rotWord*90, font=3,
col=colors[group[i]],...)
I am unable to find a way, I checked the par() of text, could not find a solution, used the underline(), did not work either, bquote(underline(..)) did not work either. Help is greatly appreciated.
