new to using PCAtools and have issues getting my data in. I have 2 data files, one is a matrix of features against samples e.g. gene expression data for a sample, and many samples, the other is a csv file of the sample metadata - where the sample came from, the patients disease status etc.
Any ideas how I get the two into PCAtools so I can create clustering and ellipses in PCA biplots etc?
I can get the matrix in, but I can't work out how to get the metadata in so it matches the matrix.
