Hi, I,m learning ropls to analysis my own metabolomics data. Thanks to ropls, I can do PCA ans PLS-DA successfully. But when I tried to use OPLS-DA method with the following code, the error occured as "Error in svd(wwMN) : infinite or missing values in 'x'". I'm sure that there is no NA, Inf and even 0 in my data, and I don't know how to deal with it. Could you help to see the reason for this error? Thank you very much.
