#' @title ass
#' @description for some given integer n generates all possible 0-1 assignment
#' vectors of 2n survey participants in such a way that exactly n of them are assigned to group 0 (control)
#' and the other n ones are assigned to group 1 (treatment).
#' 
#' @param n an integer, a number of positive responses,
#' @return a matrix with 2n columns and an appropriate
#' number of rows
#' 
#' @export

    .Call('hw6_ass', PACKAGE = 'hw6', n)
}

#' @title mode
#' @description Calculates a mode number, which is the most frequently occuring number in a given vector. 
#' If the mode is ambigous returns a smaller number of equal mode.
#' 
#' @param x a vector of integers
#' @return an integer value - mode

#' @title qgramdist
#' @description Calculates a q-gram distance \url{https://journal.r-project.org/archive/2014-1/loo.pdf} 
#' between two vectors of integers.
#' 
#' @param x a vector of single (<10 if q>1) integers
#' @param y a vector of single (<10 if q>1) integers
#' @param q an integer, q in q-gram distance
#' @return an integer value - q-gram distance, Inf if q is larger then a vector's length

#' @export
