In nbc4va: Bayes Classifier for Verbal Autopsy Data

Round values to whole numbers while preserving the sum

Description

Rounds a vector of values to whole numbers while preserving the sum (rounded if it is not a whole number) using the largest remainder method (Gallagher, 1991).

Usage

internalRoundFixedSum(v, roundSum = round)

Arguments

v	A vector of values with decimal values and a whole number sum to round.
roundSum	If the sum of the values in v is not a whole number, choose a rounding method to ensure it is a whole number.

Value

out A vector of v with the values rounded to whole numbers but with the whole number sum preserved.
