Caret produce the error: Something is wrong; all the Accuracy metric values
are missing:
logLoss AUC prAUC Accuracy Kappa
Min. : NA Min. : NA Min. : NA Min. : NA Min. : NA
1st Qu.: NA 1st Qu.: NA 1st Qu.: NA 1st Qu.: NA 1st Qu.: NA
Median : NA Median : NA Median : NA Median : NA Median : NA
We (group of three) working on an assignment and could not fix this error
from a few days. The error comes with the majority of the models while with
a few model (e.g. nb), the code works. The data is text-based
classification.
Some Warnings are:
Warning messages:
1: In train.default(y = train_label, x = train_x, method = "pls", ... :
The metric "ROC" was not in the result set. logLoss will be used instead.

Code is
m= train(y = train_label, x = train_x,
method = "pls" ,
metric = "Accuracy",
## # preProc = c("center", "scale", "nzv"),
trControl = ctrl)
p=predict(m, test_x)
confusionMatrix(p, as.factor(test_label))
