Hello
I am looking for a simple way to plot my data from a matrix (or data frame)
using a 3rd column as category to code the data points.
for example:
xyz
543240
104230
15901
203241
25781
3042340
357891
405670
45780
50531
Ideally, I'd like 0 or 1 to correspond to a color but I'd settle for a symbol
at this point. I have tried working with pch but can't get it to work.
Thanks
Kat
