[R] Different number of resamples error

[javed khan]

Hello to all

I have different train functions for NN, SVM and GBM and when I combine the
results using bwplot, it gives me the error " Different number of resamples
in each model". It gives me the results (MAE values) but using the boxplot,
it gives the error. The code is as follows:

set.seed(30218)
nnet1 <- train(results~ ., data = tr,
                method = "nnet",

                metric = "MAE",
                trControl = ctrl,

                preProc = c("center", "scale", "zv"),
                tuneGrid = data.frame(decay = (1),
                                      size = (1.3801517)))
nnet1$results

///For SVM

set.seed(30218)
svm1 <- train(results ~ ., data = tr,
                    method = "svmRadial",

                    metric = "MAE",
                    preProc = c("center", "scale", "zv"),
                    trControl = ctrl,
              tuneGrid=expand.grid(sigma = (0.5),
                                                C = c(1.348657)))
getTrainPerf(svm1)
svm1$results

//For GBM

set.seed(30218)
gbm <- train(results ~ ., data = tr,
             method = "gbm",
             preProc = c("center", "scale", "zv"),
             metric = "MAE",


             tuneGrid = data.frame(n.trees = (200.09633523),
interaction.depth = (1),
                                   shrinkage=(0.1), n.minobsinnode=(10)))
gbm$results

//Then the boxplot

rvalues=resamples(list(nnet=nnet1, svm=svm1, GBM=gbm))

bwplot(rvalues, metric="MAE")
