I've recently run a principle coordinates analysis in r with ~ 200 subjects and 17 binary variables. I've plotted my points successfully, the challenge I'm facing is that when I plot the text with the points on the graph (example attached) I'm unable to differentiate the text. Can anyone recommend away where I can display this information in a visually pleasing way? If not is there a matrix i can display?


My code below:

> data.dst <- dist(Data, method = "binary")
> cmd <- cmdscale(data.dst, k=3)
> plot(cmd)
> text(cmd, Names, pos=3)
