In ExcelFunctionsR: Imports Excel Functions to R

# MAXIFS Function from Excel
#' Basic MAXIFS function from excel
#'
#' It acts similiarly to Excel's MAXIFS function. It returns the maximum value from an array after testing for several criterias.
#'
#' @param max_range Range from where it should return the maximum value from.
#' @param criteria_range1,criteria_range2,criteria_range3,criteria_range4,criteria_range5,criteria_range6,criteria_range7,criteria_range8,criteria_range9,criteria_range10 Which range should the criteria tested for.Only criteria_range1 is mandatory,others are optional.
#' @param criteria1,criteria2,criteria3,criteria4,criteria5,criteria6,criteria7,criteria8,criteria9,criteria10 What criteria should the range be checked against. Only criteria1 is mandatory, others are optional.
#' @import base
#' @import stringr
#' @export
#' @examples
#' MAXIFS(iris$Petal.Length,iris$Species,"setosa",iris$Petal.Width,0.2)
#' @return This example returns maximum value of Petal Length of species setosa who have petal width 0.2. Function will always return numeric class.
