Hi Mixomics Team,
Thanks for providing this great stats package.
I am running a splsda on a 16S dataset, with a training and test set (independent to training set of samples). The training set has run fine (not great performance) and now I would like to test on test set.
I am running into the following error:
Error in predict.mixo_spls(Perio.train.splsda, X.test, dist = "mahalanobis.dist") : 'newdata' must include all the variables of 'object$X' In addition: Warning message: In if (all.equal(colnames(newdata), colnames(object$X)) != TRUE) stop("'newdata' must include all the variables of 'object$X'") : the condition has length > 1 and only the first element will be used
I noticed from the previous issues that predict can use another package (pls) but I don't think this is attached in my R session.
Also does the training and test set need to have the same number of variables/OTUs? As this isn't the case.
I am using mixOmics 6.7.2, R version 3.6.0.
Any assistance would be greatly appreciated, thanks
