I cannot find a "lpSVM" method. Is it possible that this is simply a misspelling? Or have you failed to create a method with that name? In the tutorial: https://topepo.github.io/caret/using-your-own-model-in-train.html the package author creates a list with that name in the section entitled "Model Components". |lpSVM <-list(type = "Classification", library = "kernlab", loop = NULL) | My further guess: you trying to run code fragments from some source without fully executing parts of a multi-step process? -- David. > trControl = fitControl, > verbose = FALSE, metric = "ROC") > > [[alternative HTML version deleted]] > > ______________________________________________ > R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code.
