How to split data into training/testing sets using sample function
There are numerous approaches to achieve data partitioning. For a more complete approach take a look at the createDataPartition function in the caret package. Here is a simple example: data(mtcars) ## 75% of the sample size smp_size <- floor(0.75 * nrow(mtcars)) ## set the seed to make your partition reproducible set.seed(123) train_ind <- sample(seq_len(nrow(mtcars)), size … Read more
