Hi, try this, plot.new() x=0.8 text(0.5, 0.5, bquote(rho == .(x))) HTH, baptiste
Aha! That does exactly what i wanted! Thanks! Jose
But does it do what it should? It's customary to use "rho" for a _population_ correlation coefficient. If your (x,y) values represent a _sample_, then it would probably be more appropriate to use the more mundane "r" or perhaps "rho-hat".
I'm talking rank correlation, Spearman's rho. Jose
Rank correlation or not, it's still customary to use "r" or "r[s]" for samples and rho or rho[s] for populations. But it's up to you, of course.
