[MORPHMET] How to project shape difference onto different PC

2018-05-18 Thread Yinan Hu
Dear colleagues, I'm trying to figure out how to break down shape differences onto individual PC axes. I have a morphospace where PC1 explains 60% of shape variation and PC2 explains 20% of variation. Two subsets of samples of particular interest do not differ much along PC1, but differs

) doesn't feel right to me as I don't think PC scores are directly comparable between different PCs. Any suggestions would be greatly appreciated. Many thanks for your time. -- Yinan Hu Postdoctoral fellow Biology Department Boston College 140 Commonwealth Ave, 360 Higgins Hall Chestnut Hill, MA
