Question

I would like to know how to implement a way to get a random sub-sample within a larger sample in R using a large collection of true random numbers (obtained using a quantum generator) those are integers which can have multiple occurrences.

Edit: Solution.

Since I needed a remise and my generated numbers in a float64 were finally unique (due to the high precision), I have used the following solution :

1) generate as many numbers as length(data)

2)

temp<-cbind(data,randomnb)
randomizeddata<-res[order(res[,2])]

3) split the dataset

Answer 1

For true random numbers, use randomNumbers from the random package.

r <- randomNumbers(number_of_samples, max = nrow(your_data), col = 1)
your_data[r, ]
