I was hoping you could help with how to properly setup data for PLS analysis. I am trying to run a simple analysis using gene expression data from two groups of samples (control vs case). While I can get through the tutorial OK, when I try to execute with my data, I am having issues with X and Y data matrix. Could you please direct me to an actual example how the data should be setup so sPSL-DA reads my files appropriately? I have tried viewing the srbct dataset and modeling after the example with no luck.
