# R/rhoMin.R In rhoR: Rho for Inter Rater Reliability

#### Documented in rhoMin

```###
#' @title Rho Min
#'
#' @description
#' This function calculates the minimum testSetLength where it is possible to get a rho less than alpha for the given parameters of rho.
#'
#' @param alpha The threshold of significance for rho (similar to an alpha level for a p value), defaulted to 0.05
#' @param inc An integer indicating by how much the testSetLength should increase each iteration
#' @param printInc A boolean indicating whether to print out each increment value with it's corresponding significance for rho
#'
#' @examples
#' rhoMin(0.2, testSetBaserateInflation = 0.33)
#'
#' #Add testSetBaserateInflation as well as changing inc and selecting printInc
#' rhoMin(0.2, inc = 5, printInc = TRUE, testSetBaserateInflation = 0.33)
#'
#' @export
#' @return  The minimum length of testSet, to the nearest multiple of inc, greater than the minimum length, that would give a value where rho less than alpha becomes mathematically possible.
