How can I split a dataset randomly into a training and testing set. I would like to have the ability to specify the size of the training set and use the remaining data as the testing set. For example 90% training data and 10% testing data split. Is there a function that will accomplish this? Thank you, -Dhiren Rutgers University Graduate Student
See ?sample. sub <- sample(nrow(x), floor(nrow(x) * 0.9)) training <- x[sub, ] testing <- x[-sub, ] HTH, --sundar
