Hi, You include no context, and I only vaguely remember your original question. You also don't include a reproducible example.
But perhaps this helps? testmat <- data.frame(x=c(1,1,2,3), y=c(2,1,3,2), names=letters[1:4], stringsAsFactors=FALSE) with(testmat, plot(x, y, pch=names)) or with(testmat, plot(x, y, type="n")) with(testmat, text(x, y, names)) Otherwise you'll have to actually follow the posting guide and pose a fully self-contained question.
