                    1Resource requests are actually off-topic for Stack Overflow. But if you search for any particular sampling method in R, you will find lots of examples. – Gregor Thomas May 04 '19 at 14:54

                    I suggest you to read the following document: https://stackoverflow.com/help/on-topic – Scipione Sarlo May 04 '19 at 15:17

                    @Gregor then suggest for stratified sampling and implementation in r – CrazyPanda May 04 '19 at 15:23

                    2Show what you have tried! Searching the [tag:r] tag for "stratified sample" gives 189 questions. Have you looked at any of them, tried any of them? [Here's the search results](https://stackoverflow.com/search?q=%5Br%5D+stratified+sample). What did you try, what didn't work, what more do you need? A request for a tutorial is not a good question for stack overflow. Get a data set. Try something. When you get stuck, share you data, share what you tried, and we will help get you the rest of the way there. – Gregor Thomas May 04 '19 at 18:42

        You can use caret package.
library(caret)
set.seed(3456)
trainIndex <- caret::createDataPartition(iris$Species, p = .8, # partition 80%~20%
                                         list = FALSE, 
                                         times = 1)

But realize that StackOverflow is a place for sharing ideas and knowledge about codes, I suggest you check out the link below for best use.
