randomnumGenerator: Random number generator

In GA4Stratification: A genetic algorithm approach to determine stratum boundaries and sample sizes of each stratum in stratified sampling

Description

This function generates random variables that don't repeat in a given range

Usage

randomnumGenerator(randomnumRange, lengthRandomnum, howManyRands)

Arguments

randomnumRange	This is the range of the random numbers randomnumRange can be something given as: randomnumRange=1:487 or randomnumRange=c(6, 12, 36, 67, 87, 146, 267) therefore length of the randonnumRange in the first case is 487 in the second case is 7, defining the index of the randomnumRange to be swapped
lengthRandomnum	This is the length of the random number range
howManyRands	Number of random values

Value

An array of different random numbers

Examples

randomnumGenerator(c(1,3,5,7,9,15,21),7,3)

function(randomnumRange,lengthRandomnum,howManyRands)
   {

  	for (i in 1:(howManyRands))
   	{
		integer=sample(lengthRandomnum-1,1)
		tmp=randomnumRange[integer]
		randomnumRange[integer]=randomnumRange[i]
		randomnumRange[i]=tmp
   	}
	return(randomnumRange[1:howManyRands])
   
   }
