search for: valaddind_byyear

Hello, I would like to label outliers (or all dots) in a plot plot(as.matrix(ValAddInd_byYear), as.matrix(Cons_Elec_Ind_byYear)) ideally by the 30 different row.names, but anything else (x or y values, for example) would already be helpful. I've tried various things with pch, but they didn't work and I can't find anything else. Any hint appreciated! Thanks, Katrin
