Round to a Multiple of 4

This function rounds the given value n to the nearest value created by r2.

roundr(n, r2 = c(4, 512, 4))

Arguments

n	The number you want to round
r2	Encodes the values plugged into the seq() function with the elements being: The minimum value to be rounded to The maximum value to be rounded to, and The step/multiple to be incremented by. Ideally, 1 and 2 should be a multiple of 3

Value

A integer rounded to the nearest multiple of the third element in r2

Details

roundr() works by creating an array and finding which number n is closest to. r2 contains all the input arguments for the seq() function (being the min, max and step args) which are then parsed to seq() to create an array of values. roundr() then takes the number to be round: n, and finds the minimum absolute difference between it and all values in the sequence created by r2. Finally the number in the array closest to n is returned as the 'rounded' value.
