For discussions related to modeling, machine learning and deep learning. Related packages include caret, This issue came while modelling and running lm code?
Can you tell me the issue
model <- train(admissions ~ ., data = trainData, method = "lm")
Without a reprex it is hard to know what is happening here.
My best guess is that you are including a ID variable as a categorical variable, which is then dummied, leading to a very large matrix that you are unable to allocate. If that is the case, remove that variable from trainData and try again.
