Firstly, thanks for developing the useful mixomics package!
I am writing to ask about two problems when I was trying to do the sPLSDA analysis. Basically I have two datasets, both of which I am using the first 1440 columns as X and the last column as Y. For the first one, I have some empty predicted values when Y should only have two classes; for the second one, the error message keeps popping up when I am trying to tune the model (in the tune.splsda).
I would really appreciate your help and suggestions in fixing this! Thanks in advance and take care.
