I want to do a pca plot of 20 samples I measured. For this I used gscatter. However, I want
1) to color my samples with 7 colors for the different type of organisms i measured and in addition
2) I want to give symbols for another variable called, dead or alive where I want to use square for dead and triangles for alive
How can I create a pca plot showing what I described above? do I need to use something else than gscatter?

gscatter will accept multiple grouping variables, in your case organism & dead/alive. There is an example in the gscatter documentation--search for "Scatter Plot with Multiple Grouping Variables". I believe you specify 14 colors and 14 symbols for your 7*2=14 combinations of the two grouping variables.

Hi Kim,
You are welcome. That does sound pretty complicated, so extra-good that you got it working.
