To **sample** observations (rows) from a data frame or a list, we don't **sample** the rows directly but the indices into an object. head (mtcars) # step 1: create an index vector for the elements/rows index <- seq_len (nrow (mtcars)) # step 2: **sample** the index vector set.seed (12) #to obtain a random **sample** of 10. Description Creates possibly balanced **samples** by random over-sampling minority **examples**, under-sampling majority **examples** or combination of over- and under-sampling. Usage ovun.**sample** (formula, data, method="both", N, p=0.5, subset=options ("subset")$subset, na.action=options ("na.action")$na.action, seed) Arguments formula. It's a must have tool for machine learning projects in **R**. For more information about the caret **R** package see the caret package homepage. 2. Load The Data We are going to use the iris flowers dataset.
