I did something very similar in ggplot2 about a year ago. Use the unique sampling location from the species count data (rownames) as a factor column, and then use that in a geom_color or geom_shape add on to qplot
untested: library ggplot2 a <- metaMDS(foo, k=3) b <- rownames(foo) d <- data.frame(b , a$points) qplot(axis_1, axis_2, data=d, colour="b") something like this may work - it would be nice to have a reproducible example Stephen On Wed, Sep 2, 2009 at 1:11 PM, Wade Wall<wade.w...@gmail.com> wrote: > Hi all, > > Is there a way in R to plot points using symbols as defined in another > vector without adding a separate points line for each symbol?
