Hi everyone,

I have a PCA plot that I'm writing about in the text.  There were so many
symbols in different colours on it that I didn't include a legend in the
plot as it would be useless.  So what I was hoping to do was to talk about
each set of replicates in the text and when I do that, use their coloured
symbol in the text.  So what I want to do is to get R to create some high
quality picture files of the symbols with the colours I tell it to.

Does anyone have an idea about the best way to go about this?  I created a
graph of the symbols and tried to use photoshop to cut them out, but it's
laborious and the quality is not the best.  I just want small sharp symbols.

Thanks
