I can't get the fine tuning right with my legend. I get an extra legend
element "10" which is the point size in my plot. Can someone help me get rid
of this extra element? Additionally I would also like to reduce the size of
the legend.

If you want to reproduce my figure you can  download my data in csv format
here
<https://github.com/scoyoc/EcoSiteDelineation/blob/master/VegNMDS_scores.csv
>
.

Here is my code...

>veg.nmds.sc = read.csv("VegNMDS_scores.csv", header = T)

>nmds.fig = ggplot(data = veg.nmds.sc, aes(x = NMDS1, y = NMDS2))
>nmds.fig + geom_point(aes(color = VegType, shape = VegType, size = 10)) +
>  scale_colour_manual(name = "Vegetation Type",
>                      values = c("blue", "magenta", "gray50", "red",
> "cyan3",
>                                 "green4", "gold")) +
>  scale_shape_manual(name = "Vegetation Type", values = c(15, 16, 17, 18,
> 15, 16, 17)) +
>  theme_bw() +
>  theme(panel.background = element_blank(), panel.grid.major =
> element_blank(),
>        panel.grid.minor = element_blank(),
>        legend.key = element_rect(color = "white")
>        )

I have been messing around with
>  theme(..., legend.key.size = unit(1, "cm"))
but I keep getting the error "could not find function unit". I'm not sure
why, isn't unit supposed to be part of the legend.key argument?

... and the resulting figure...

Thanks for the help.
