Hi, I have matrix of 300,000*115 (snps*individual). I ran the PCA on the covariance matrix which has a dimention oof 115*115. I have the first 100 individuals from group A and the rest of 15 individuals from group B. I need to plot the data in two and 3 dimentions with respect to PC1 and PC2 and (in 3D with respect to PC1, PC2 and PC3). I do not know how to have the plot ploting the first 100 points corresponding to group A in red (for example) and the rest of the 15 points in Blue? i.e I want the each group in a diffrent color in the same plot. I appreciate if someone can help.
