Split a dataframe for training and testing sets

Description

This function splits automatically a dataframe into train and test datasets. You can define a seed to get the same results every time, but has a default value. You can prevent it from printing the split counter result.

Usage

msplit(df, size = 0.7, seed = 0, print = TRUE)

Arguments

df	Dataframe
size	Numeric. Split rate value, between 0 and 1. If set to 1, the train and test set will be the same.
seed	Integer. Seed for random split
print	Boolean. Print summary results?

Value

List with both datasets, summary, and split rate.
